Hi,
I have some years using Alarm Clock Xtreme but now I can't see the alarm ringing on my screen when my s21 ultra screen is locked. This means that every time the alarm start to ring I have to unlock the phone then finish or snooze it. I should be able to do that even if my phone screen is locked

Allowing "Appear on top" permission fix the problem.
Don't know why this was working before. Anyway, it works now. I will sleep a little bit more in the morning
