I’ve been having this problem for months and it REALLY bothers me. Whenever I’m having an iMessage conversation, I get a notification on my watch when someone replies. Sometimes I even get a notification for a message I sent. This is with the screen on and in iMessage. It was never like this when I first got the watch. It was smart enough to know not to receive a notification when my iPhone screen is on. I erased the watch and restored from a backup but that didn’t help. Anyone else having this issue?
