You open the app.
Everything works.
Messages load.
Features respond.
No errors appear.
But one thing is missing.
No notifications.
No alerts.
No push messages.
No reminders.
It feels like the app went silent overnight.
Why Notifications Stop While the App Still Works
- Notification permissions were disabled
- Battery optimization blocked background alerts
- Focus / Do Not Disturb mode silenced pushes
- App notification categories were turned off
The app itself is functional.
Only the notification channel is restricted.
Common Triggers Users Miss
- System updates resetting notification settings
- Installing battery saver or cleaner apps
- Changing device notification priorities
- Accidentally muting alerts from the lock screen
These changes often happen silently.
How to Restore Notifications
- Re-enable notifications in device settings
- Disable battery optimization for the app
- Turn off Focus / Do Not Disturb mode
- Check in-app notification preferences
If alerts stopped but the app still works,
the issue is almost always permission or system control — not the service itself.
