I have an iPhone 13, running iOS 15.1, and I'm not being alerted to push notifications that arrive while the device is asleep.
When I tap the screen, the display lights up and the message preview is there, so I know it's receiving them, but it's not notifying me.
If the phone is awake, and at the Home screen, and a push notification arrives, the phone makes the notification sound and shows the notification as expected.
This is a problem because it applies to text message notifications; I'm missing texts because the phone isn't notifying me. It also applies to notifications from apps.
This is new to iOS 15.
Things I've checked:
- The physical switch that turns on "Silent Mode" is Off.
- In Settings/Notifications, "Scheduled Summary" is Off
- In Messages settings, "Allow Notifications" is On and Sound is set to "Note".
- In "Sounds & Haptics", the "Ringer and Alerts" volume is about halfway up, and plenty loud when I test it by tapping the drag handle.
- No "Focus" is on.
- No Sleep Schedule is configured in the Health app.
- "Allow Notifications" is On for the specific apps I'm testing with, and the "Sounds" switch is On.
I can't see any reason the phone is delivering notifications silently when the screen is locked; please let me know what else I can try.
