An app's notifications are not arriving
One app has gone quiet: its messages or alerts only appear when you open it, or arrive very late. The cause is usually one of a few settings — the app's notification switch, Do Not Disturb, or battery optimisation.
Does this sound familiar?
- Messages only appear when I open the app
- I get no sound or banner from one particular app
- Notifications from an app arrive hours late
- An app stopped notifying me after an update or a settings change

Method for this problem
Check an app's notification and permission settings
Work through the settings that can silence one app: its notification switch and categories, the permissions it needs, Do Not Disturb and modes, and — only if notifications are still late — battery optimisation, which can delay alerts for apps you rarely open.
