I remember the first morning after coming down with COVID (and feeling quite wrecked) I woke up at 11‑12, still seeing the stop/snooze buttons on my alarm on the iphone that has been set to 8 am...Honestly the number of things that can go wrong with alarms is one of the very most frustrating things to me about iOS/watchOS. My old, brutally loud "BEEEEP BEEEEP BEEEEP" Zenith alarm clock that I had when I had a job where lateness would lead to loss of work was far more reliable. If an alarm is set, it should take precedence over EVERYTHING else.
And no, I am pretty sure I haven't pressed the snooze every 9 minutes for four hours!
Give me back my good old mechanical clock.
