It was easy to set up. Alarms went off for me but the setting to use volume buttons to snooze doesn't work no matter what I do. The biggest annoyance for me is that when I set a timer it doesn't alarm when the timer expires. Instead when I check your phone to see how much time is left it shows a negative amount of time. When I click on that time to open the app suddenly it starts alarming. I'm using a brand new galaxy s22 plus.
