Wanted to see if anyone else had this issue. I’ve had an Apple Watch Series 7 for about 2 years now and have been using the vibrating alarm that whole time with no issues. Ever since the new watchOS came out though, there have been multiple times that I’ve slept though the alarm. It’s to the point now that I’ve started using an audible alarm clock as a backup. A lot of times I’ll wake up 20 mins or so after my alarm is supposed to go off, and I see the notification on my watch to cancel the alarm, but the watch isn’t vibrating for some reason. I love the apple watch, but I’d consider getting something else if the vibrating alarm is no longer reliable.
