I don’t know if I’m posting this in the right place, but for the past 2 days my CMF Phone 1 running e/os 3.2-a14 has randomly started turning on alarms at different times, as shown on the lock screen. When I open up the clock app however, there is no alarm set, and no alarm goes off either when the time comes. The time the alarm is set to changes as well, and it’s only ever indicated on the lock screen.
This is a user forum. To report a bug to devs one would Report an issue.
Maybe try to delete storage in the clock app. Use Settings > Apps > See all apps > Clock > Storage and cache > Clear storage. (All of your own clock and alarm related settings will reset and lost.)
