Usability problem

[blaugrau3001]

Its not really a bug, but when you use the auto-mute feature wouldnt work until you turn on the permission for time aka Alarms and reminders. The problem is you are getting any notice that you need to do do that.
I am new to the app but I think this is the reason why the feature didn't worked for me.
Unfortunately I am not able to test more, because I have holidays, but maybe some else can test it to verify that this is the reason.
