Lately my alarm has not been working properly on my Galaxy S7. I use "Android Sleep" app, which had been working fine for a few months until this recent issue started. The phone and app are up to date.

Details:
Repeating alarm set to go off at 6:25AM every Tue,Wed,Thur,Fri. The alarm will not go off on Tue. It does work fine on Wed-Fri.

I've tried deleting and re-adding the alarm and the entire app and still have the issue.

Any ideas why this is the case?

My guess is Sat-Sun-Mon is the three days of non-use detected by your phone, which is then putting it to sleep. You open the app Tuesday trying to find out why it didn't work (in-use), which allows it to work for the next three days.

Try going to Settings > Device maintenance > Battery, scroll to the bottom to get to "unmonitored apps", then tap "add apps" and select your alarm.
