Hi!
As the subject says, my prefered alarm app "alarm clock xtreme pro" only shows up in the notifications, when the alarm starts. So I have to pull down the notification bar and then stop/snooze the alarm.
Are there any other users facing this problem? It's really odd, when you have to do this every morning to stop the alarm so I switched to the build-in alarm function for now. But I really like to have my paid app back working again.
I had that problem with android9 as well, so I think it is a ZenUI problem.
