Hello, this is Alarmy team.
Did the dismiss screen stopped popping up after you updated your device to Android 10?
It's probably because from Android 10, third-party apps cannot display its screen above the lock screen unless the user explicitly agreed to give such permission. You might face problems when trying to open Alarmy while the alarm is blaring. 😰
In case the OS version of your device is 10 or higher, find Alarmy in [Device settings > Application] and grant Alarmy the permission called "Draw over apps." (The exact name of the permission may be a bit different!)
Once you grant the permission, Alarmy's dismiss screen will automatically appear on top so that you can easily work on dismissing the alarm.
If you need any help following the guide above, please send us a feedback from [Settings tab > Send Feedback].
We will keep getting better and better. Don't forget that you are the one that can help us do so. 😉
