Looks like you're awake
This very energetic haptic notification happens during sleep focus:
"Looks like you're awake. Do you want to turn off the alarm and sleep focus?"
There are many people who prefer to gently wake up or doze off in bed before the alarm goes off and this is annoying them. Myself I had to stop wearing the watch because of this.
There is no way to disable this notification.
I do not want to manually turn on/off a custom focus state for when I sleep, because when I would forget to do either I get woke up by a random notification at 3am or my notifications would be disabled the entire day.
I do not want to use custom alarms because they are very loud, the good morning ones have more gentler choices.
I'm pretty sure no user ever requested this "feature", how hard can it be add an option to disable it? It would make everyone happy.
