When Instagram notifications stop working, the problem is not always inside the Instagram app. Notifications can be blocked at several levels, including your phone’s system settings, Instagram’s notification preferences, battery-saving features, Focus or Do Not Disturb modes, and the app itself.
The right fix depends on where the notification is being blocked. A message notification, for example, may fail because Instagram notifications are disabled, while notifications work normally for other activity. In other cases, everything is enabled, but the phone prevents Instagram from running properly in the background.
This guide explains how to fix Instagram notifications not working on Android and iPhone, starting with the most common causes and moving toward more advanced troubleshooting steps.
Check Whether Instagram Notifications Are Enabled in the App
Before changing your phone settings, check Instagram’s own notification controls. Instagram allows you to manage different types of alerts separately, so it is possible for message notifications to be enabled while notifications for likes, comments, Live videos, or other activity are turned off.
- Open Instagram.
- Tap your profile picture in the bottom-right corner.
- Tap the menu icon in the top-right corner.
- Open Notifications.
- Check whether Pause all is enabled.
If Pause all is turned on, Instagram temporarily stops sending notifications. Disable it and check whether alerts begin arriving again.
Then review the individual notification categories. Depending on the version of Instagram, these can include:
- Posts, Stories and Comments
- Messages and Calls
- Following and Followers
- Live and Reels
- From Instagram
Open the category related to the notifications you are missing and make sure the appropriate alerts are enabled.
If you are only having trouble with one type of notification, this is one of the first places to check. For example, if Instagram Direct messages do not trigger alerts but likes and comments do, the problem may be limited to the Messages and Calls settings rather than your phone.
Make Sure Your Phone Allows Instagram Notifications
Even when notifications are enabled inside Instagram, your phone can block them completely.
On iPhone
- Open the Settings app.
- Tap Notifications.
- Find and select Instagram.
- Turn on Allow Notifications.
You should also check how notifications are delivered. Make sure at least one alert location is enabled, such as:
- Lock Screen
- Notification Center
- Banners
If Instagram notifications arrive but you do not notice them, check the Sounds setting as well.
A common mistake is assuming notifications are disabled because they do not appear as banners. They may still be arriving silently in Notification Center or on the Lock Screen.
On Android
The exact steps vary by phone manufacturer and Android version, but the general process is similar:
- Open Settings.
- Go to Apps or Apps & notifications.
- Select Instagram.
- Tap Notifications.
- Turn on notifications.
Android also allows individual notification categories to be controlled separately. Depending on your device and Instagram version, you may see categories for messages, comments, live videos, calls, and other activity.
Make sure the specific category you need is not disabled or set to silent.
If you recently updated Android or restored your phone from a backup, review these settings even if you are certain notifications were previously enabled. App permissions and notification preferences can occasionally change after a major update or device migration.
Check Focus, Do Not Disturb, and Other Notification Filters
Your phone may be receiving Instagram notifications but hiding or delaying them because a notification mode is active.
Check Focus on iPhone
Open Settings > Focus and check whether a Focus mode is currently enabled.
A Focus mode can silence notifications from selected apps. If Instagram is not allowed through the active Focus configuration, its alerts may not appear normally.
You can temporarily turn off the Focus mode and send yourself a test message on Instagram. If the notification appears immediately, the Focus settings are responsible.
Also check whether a Focus mode is scheduled automatically. Some modes activate based on time, location, or specific apps, which can make the notification problem seem inconsistent.
Check Do Not Disturb on Android
Open your phone’s Settings and look for Do Not Disturb, usually under Notifications, Sounds, or a similar category.
Turn it off temporarily and test Instagram again.
Some Android phones allow notification exceptions, meaning calls or selected apps can still send alerts while other notifications are silenced. Check the exceptions if you want to continue using Do Not Disturb without missing important Instagram messages.
Turn Off Battery Restrictions for Instagram
Battery optimization is a frequent reason Instagram notifications stop arriving until you open the app.
Phones reduce background activity to save battery. If the operating system restricts Instagram too aggressively, the app may not receive new activity promptly. When you open Instagram, the app reconnects and suddenly displays the notifications you should have received earlier.
That pattern is an important clue. If Instagram notifications only appear after opening the app, background restrictions are more likely than a simple notification setting problem.
On Android
Open:
Settings > Apps > Instagram > Battery
The wording varies by manufacturer. Look for an option such as:
- Unrestricted
- Allow background usage
- Don’t optimize
- Unrestricted battery usage
Avoid disabling battery optimization for every app on your phone. Change the setting only for apps where delayed notifications are causing a real problem.
Samsung, Xiaomi, OnePlus, and other manufacturers may also include additional battery management features that close apps running in the background. If the standard Android battery setting does not fix the problem, check your phone’s battery or app management section for restrictions affecting Instagram.
On iPhone
Go to:
Settings > General > Background App Refresh
Make sure Background App Refresh is enabled and that Instagram is allowed to refresh.
Also check Low Power Mode under Settings > Battery. Low Power Mode reduces some background activity. It does not necessarily stop all Instagram notifications, but testing with it disabled can help determine whether power-saving restrictions are contributing to delayed alerts.
Check Your Internet Connection
Instagram needs a working internet connection to receive new activity and update the app.
If notifications are delayed, switch between Wi-Fi and mobile data and test again. For example, send a message to the affected account and see whether the notification arrives on each connection.
If Instagram works normally when you open the app but notifications are consistently delayed on one network, the issue may involve the connection rather than the notification settings.
Also check whether a VPN, firewall, private DNS service, or aggressive data-saving feature is interfering with Instagram’s network activity. Temporarily disabling these tools for testing can help identify the cause.
Do not permanently disable a security or privacy tool unless you confirm it is responsible for the problem. The goal is to isolate the source of the issue.
Turn Off Data Saver or Restricted Background Data
Data-saving features can limit how apps use the internet in the background.
On Android, open Instagram’s app settings and look for Mobile data, Data usage, or a similar option. Make sure background data is allowed.
Some phones also include a system-wide Data Saver feature. If it is enabled, you may need to allow Instagram to use unrestricted data.
On iPhone, check that Instagram is allowed to use mobile data under:
Settings > Cellular
If you mainly rely on mobile data and Instagram’s cellular access is disabled, the app may not update properly when Wi-Fi is unavailable.
This setting is particularly relevant if notifications work at home on Wi-Fi but stop when you leave the house.
Update Instagram
An outdated version of Instagram can sometimes cause notification problems, especially after a major operating system update.
Open your phone’s app store and check for an Instagram update.
Updating the app can fix known bugs and compatibility problems. It is also useful before trying more disruptive steps, such as reinstalling Instagram.
After updating, restart your phone and test notifications again.
A restart is simple, but it can resolve temporary problems involving background processes or a system service that handles notifications.
Clear Instagram’s Cache on Android
If Instagram is behaving inconsistently, clearing its cache can remove temporary files without deleting your account.
- Open Settings.
- Go to Apps.
- Select Instagram.
- Open Storage.
- Tap Clear cache.
The exact names may differ slightly depending on your phone.
Avoid selecting Clear data unless you are prepared to sign back into Instagram and reset some app preferences. Clearing the cache is usually the safer troubleshooting step because it does not erase your account.
iPhones do not provide the same general cache-clearing option for individual apps. If you are using an iPhone and suspect damaged temporary app data, reinstalling the app is usually the more practical option.
Check Whether Instagram Is Signed In on the Correct Account
If you use multiple Instagram accounts, make sure you are testing notifications for the correct one.
Each account can have different notification preferences. You might receive notifications for one account while another remains silent.
Open Instagram and switch to the affected account. Then check the notification settings again.
This issue can be easy to miss because Instagram keeps multiple accounts accessible inside the same app. A notification setting may appear correct when you are viewing one account while the problem affects another.
Check Message and Chat Notifications
If only Instagram messages are not showing notifications, check the conversation itself.
Instagram allows certain chats to be muted. Open the affected conversation and review its notification settings.
Also check whether the sender has sent a normal message. Some message types, disappearing content, and certain interaction types may behave differently from standard Direct messages.
If notifications are missing from only one conversation, but messages from other accounts trigger alerts normally, a muted chat or conversation-specific setting is more likely than a phone-wide notification problem.
Sign Out and Back Into Instagram
Signing out can refresh the app’s connection to your account.
Before doing this, make sure you know your login details and have access to any two-factor authentication method connected to the account.
Then:
- Open your Instagram profile.
- Open the menu.
- Scroll to the login options.
- Sign out of the affected account.
- Close Instagram completely.
- Restart the phone.
- Sign back in.
Test notifications after logging in again.
This step is not necessary for every notification problem, so it is better used after checking the simpler settings first.
Reinstall Instagram
If notifications still do not work, reinstalling Instagram can help resolve corrupted app files or settings that are not corrected by an update.
On iPhone
Delete Instagram, restart the phone, then install it again from the App Store.
On Android
You can uninstall and reinstall Instagram from Google Play. On some phones, you may also have the option to uninstall updates if Instagram came preinstalled, although this is less common.
After reinstalling:
- Sign in to your account.
- Allow notifications when your phone asks for permission.
- Open Instagram’s notification settings.
- Verify that the notification categories you need are enabled.
Do not ignore the permission prompt during setup. If you deny notification access, Instagram may appear to be configured correctly inside the app while Android or iPhone blocks every alert.
Check for Phone and System Updates
If the problem started immediately after a phone update, it may be related to a temporary compatibility issue. Installing the next available system update can sometimes resolve these problems.
Check for updates under your phone’s software update section.
However, avoid assuming every notification problem is caused by the operating system. If only Instagram is affected, start with Instagram’s settings and app-level troubleshooting before resetting broader phone settings.
What to Do If Instagram Notifications Only Work When You Open the App
This specific symptom usually points toward a background activity problem.
Start by checking:
- Battery optimization or battery restrictions.
- Background data permissions.
- Data Saver or Low Data Mode.
- Background App Refresh on iPhone.
- Your internet connection.
- Battery-saving features added by your phone manufacturer.
On Android, the most important setting is often the battery configuration for Instagram. Set the app to unrestricted or remove unnecessary background restrictions, then test it for several minutes without opening the app.
Do not test immediately after changing multiple settings at once. If possible, change one likely cause, then send a test message or trigger a notification. This makes it easier to identify what actually fixed the problem.
What to Do If You Receive Notifications but There Is No Sound
If Instagram notifications appear but remain silent, the issue is different from notifications not working entirely.
On iPhone, check:
Settings > Notifications > Instagram > Sounds
Also check your phone’s sound settings and whether a Focus mode is silencing alerts.
On Android, open Instagram’s notification settings and inspect the relevant notification category. Android categories can have their own sound and importance settings, so message notifications may behave differently from other Instagram alerts.
Make sure the notification category is not set to Silent.
Common Mistakes That Can Prevent Instagram Notifications From Working
Several troubleshooting steps are often skipped because the settings are not immediately obvious.
One common mistake is checking only the Instagram app settings. Both the app and the phone must allow notifications.
Another is disabling battery restrictions without checking background data access. If Instagram cannot use the internet properly in the background, removing battery optimization alone may not solve delayed notifications.
Reinstalling the app too early is also unnecessary in many cases. Check notification permissions, Focus or Do Not Disturb modes, battery restrictions, and network settings first.
Finally, avoid changing every setting at once. If notifications start working afterward, you will not know which setting caused the problem, making future troubleshooting more difficult.
When the Problem May Be on Instagram’s Side
Sometimes the issue is not caused by your phone at all.
If several people are reporting missing or delayed Instagram notifications at the same time, the problem may involve Instagram’s servers or a temporary app issue. In that situation, repeatedly reinstalling the app or resetting your phone is unlikely to help.
You can check whether other Instagram features are also affected. Problems with message delivery, feed updates, login, or other functions may indicate a wider service issue.
If the problem affects only your account and all phone settings appear correct, reporting the issue through Instagram’s support options may be appropriate. Include useful details such as the type of notification that is missing, your phone model, operating system version, and the version of Instagram you are using.
Conclusion
To fix Instagram notifications not working, start with the simplest checks: make sure notifications are enabled in both Instagram and your phone’s settings, then check Focus or Do Not Disturb modes.
If notifications only appear after opening Instagram, focus on background restrictions, battery optimization, background data, and network settings. Updating the app, clearing its cache on Android, signing out, or reinstalling Instagram can help when the problem is caused by damaged app data or a software issue.
The most effective approach is to test notifications after each major change. That prevents unnecessary resets and helps you identify whether the problem is caused by Instagram, your phone’s notification settings, or the way the operating system manages the app in the background.
