My iPhone 11 Pro Max recently has started randomly having an alarm go off despite no alarms being on and all alarms deleted

1. Do you have any third party Alarm App installed which is interfering with the default Alarm app?
2. Do you have BedTime alarm set?
3. Was there any Alarm symbol on status bar on top (Watch the 1st GIF below)
4. Check your Reminders Today Notifications (Watch the 2nd GIF Below)

Similar issue here. I have checked all the things suggested. Even deleted all alarms and reset them and still sometimes they don't go off, sometimes they go off even though they have been deleted, and sometimes the Snooze function continues over and over even though I turned it off when I set the alarm. It has been happening since the last software update. It is super annoying and also problematic when you can't trust that your phone will notify you of important appointments. I really, really hope that there is a fix for this soon.

I have recently been experiencing the same issue. It was annoying as heck and I laughed this morning when the same thing happened to a host on Good Morning America. I have discovered that when it happens if I hold down the power button long enough for Siri to ask what I need, the alarm will go off. I pray that this is because Apple is working diligently to resolve this issue.
