Instagram message notifications usually stop because of a setting in one of three layers: Instagram's own notification settings, your phone's system settings, or a background restriction such as Focus mode, Do Not Disturb or battery optimisation. If alerts only arrive once you open the app, start with the background and battery checks in Fixes 3 to 5.
Why Instagram DM notifications are a 3-layer problem#
Instagram DM notifications can fail at three different levels:
- Instagram's own notification settings - inside the app
- Your phone's system notification settings - iOS Settings or Android Settings
- Your phone's background processing rules - Focus Mode, Do Not Disturb, Battery Optimisation
All three layers must be configured correctly for notifications to work. A single wrong setting at any level silences everything. Work through all fixes below even if you're sure one layer is fine.
Fix 1: Check Instagram's in-app notification settings#
This is the most common culprit.
On both iOS and Android:
- Open Instagram and tap your profile photo (bottom right).
- Tap the three lines (hamburger menu) in the top right.
- Tap Settings and Privacy > Notifications.
- Tap "Messages and calls".
- Ensure "Message Requests" and "Messages" are both set to "On" (not "Off" or "None").
Also check the "Direct Messages" section in the main Notifications screen - there's sometimes a separate toggle for DM notifications that overrides the others.
Fix 2: Check iOS system notification settings (iPhone only)#
- Open the Settings app on your iPhone.
- Scroll down and tap "Notifications".
- Scroll to Instagram and tap it.
- Ensure "Allow Notifications" is toggled ON.
- Under "Alerts", enable Lock Screen, Notification Centre, and Banners.
- Ensure "Sounds" is on. If it's toggled off, DMs arrive silently.
- Set the Banner Style to "Persistent" rather than "Temporary" if you want notifications to stay on screen until you dismiss them.
Fix 3: Disable Focus Mode or configure it to allow Instagram (iPhone)#
Focus Mode (introduced in iOS 15) is the single biggest cause of "sometimes I get notifications, sometimes I don't" on iPhone. When a Focus Mode is active, apps not on your allowed list are silenced.
To check if Focus Mode is the culprit:
- Swipe down from the top-right of your screen to open Control Centre.
- Look for a moon, Do Not Disturb, Driving, or Focus icon. If one is highlighted, a Focus Mode is active.
- Tap it to turn it off. Then check if Instagram notifications return.
To allow Instagram notifications during a Focus Mode:
- Settings > Focus > select your Focus mode (e.g. Work, Personal).
- Tap "Apps" under "Allowed Notifications".
- Add Instagram to the allowed apps list.
Also check: Settings > Focus > Focus Status. If "Share Focus Status" is on, some apps see your Focus and suppress their own notifications. Turn this off for Instagram.
Fix 4: Check Do Not Disturb (both platforms)#
Do Not Disturb is a simpler version of Focus Mode on older iOS versions and Android. It silences all notifications from non-allowed contacts.
iPhone: Settings > Focus > Do Not Disturb. Ensure Instagram is in the allowed apps, or turn Do Not Disturb off during your working hours.
Android: Settings > Sound & Vibration > Do Not Disturb. Ensure Instagram is in the exceptions list, or set a schedule that doesn't cover your working hours.
Fix 5: Fix Android battery optimisation silencing Instagram#
Android's battery optimisation aggressively kills background processes to save battery. Instagram can't deliver push notifications if it's been killed. This is especially common on Xiaomi (MIUI), Huawei (EMUI), Oppo, and Samsung devices with power-saving mode enabled.
Fix:
- Go to Settings > Apps > Instagram > Battery.
- Select "Unrestricted" or "Don't Optimise".
- The path varies by manufacturer - search "[your phone brand] disable battery optimisation for specific app" if you can't find it.
On Samsung specifically: Settings > Device Care > Battery > Background usage limits > Never sleeping apps - add Instagram here.
Fix 6: Re-enable notifications after Instagram update#
Instagram occasionally resets notification preferences after a major app update. After updating Instagram, your previously configured notification settings may be back to defaults.
Fix: After any Instagram update, re-check your in-app notification settings (Fix 1) and your iOS/Android system settings (Fix 2) to confirm nothing got reset.
Fix 7: Log out and back in#
Sometimes Instagram's push notification token (a unique ID that links your account to your device's push notification system) gets corrupted or expired. Logging out and back in regenerates a fresh token.
Steps:
- Instagram > Profile > Settings and Privacy > Log Out.
- Wait 30 seconds.
- Log back in.
- When prompted to allow notifications, tap "Allow".
Fix 8: Check for multiple devices or active sessions#
Instagram sends push notifications primarily to the device you most recently used. If you've logged in on a new phone, a tablet, or Instagram Web, your main phone may have been deprioritised.
To see all active sessions:
- Instagram > Profile > Settings and Privacy > Security > Active Sessions (or "Where You're Logged In").
- Log out of any devices you no longer actively use.
Reducing the number of active sessions means notifications reliably go to your primary device.
Fix 9: Clear the app cache (Android)#
A corrupted Instagram cache can prevent push notifications from registering correctly.
- Settings > Apps > Instagram > Storage.
- Tap "Clear Cache" (not "Clear Data" - that logs you out).
- Reopen Instagram.
On iOS, clearing cache requires offloading the app (Settings > General > iPhone Storage > Instagram > Offload App) and reinstalling.
For businesses: getting every DM without relying on push notifications#
If your business depends on Instagram DMs and you can't afford to miss any because of notification issues, the real solution isn't to keep tweaking notification settings - it's to move to a proper inbox.
Push notifications are designed for individuals checking their own Instagram. For businesses handling dozens or hundreds of DMs per day, you need the Instagram Messenger Platform API connected to a shared inbox.
Instant Reply connects directly to this API. Inbound DMs that Meta delivers to your connected account arrive in your team inbox through the official API, so your team does not depend only on the Instagram app's push notifications. AI drafts a reply for your team to review and send. Works across WhatsApp, Instagram, and Messenger in one place.
