One thing that I’ve done with my watch is turn off the “coaching” notifications. It drove me crazy that if I was the least behind with activity for a particular day, it would pester me. It was especially irritating that sometimes it would bug me as soon as I put it on my wrist, first thing in the morning, before I even had a chance to do anything. Something is off for with the algorithm for the watch, if it cant figure out that you had just gotten up.
I still leave other notifications on, such as when those that I get when I close rings, or the breathe reminders.
