When I close the Clock app the alarm no longer works. I have noticed that closing the app causes the little alarm icon to go away (indicating the alarm is no longer on). This never happened before, the alarm icon would stay on even if the app were not open.

I have cleared the clock app cache, restarted the phone, reset all settings and restarted again all to no avail.

This is on a Samsung Galaxy S22 Ultra, Android 14 and it is the native Clock app that came with it.

Any ideas would be appreciated.
