I overslept because iOS 14 disabled my alarm
Interestingly enough, nothing like this happened to me, and I'm using exact same features as OP. Bad luck I guess.However, it reminds me about some other situation that I'd like to share as it amuse me to this day.Some time ago I was traveling to my clients city. I was provided with a flat of one of coworkers who - at the same time was delegated elsewhere. So that was kind of AirBnB but it was all "paid" by company (in a way, that he got compensation and I had place to stay).I went to sleep fairly late and barely shut my eye when at 2am his Android tablet started to ring. I have no idea what was up with it, was it default alarm or some custom one, but there was no way for me to disable it. None of the physical buttons worked and every touch interaction spawned the lock screen through which I couldn't get past. On top of it, the sound was getting louder and louder. It didn't ring for 20 minutes when the police came knocking. Someone complained about the noise. I said that the device isn't mine and I'm only taking care of friend's flat and that there is nothing I can do about it. Showed device to them, we fiddled together with it but couldn't turn it off neither. Police wanted to hand me a ticket, but that wasn't easy. I was foreigner so they had to collect on spot. Once they confirmed that they decided to not make me any troubles and asked me to try and to muffle the tablet.After 3h of constant noise it seemed like device decided to stop ringing by itself.Since I was awake full night, I took day of and notified the client that it's either hotel for me or I'm going back home, cause I decline to be in the same place as the dreaded device to which they agreed. That almost was the end of the story, but week later I learned it wasn't end of it.Coworker, the owner of the device (who refused to provide me with the code, since it can't be that bad), came back to his door which kicked out by the firefighters. It seemed like neighbors called the police again day/days later. Police couldn't get in but they heard the alarm so they called the firefighters who assuming that one of the smoke alarm went off decided to break in to find only ringing tablet.To this day I rather not being woken up than suffer through the Alarm from Hell.
