I just upgraded from a Note 9 to a Note 20 and had to reset my watch so it would connect to the Note 20. Since then, I receive text notifications from both my default app (Message+) and Samsung Messages on my watch only. I also keep getting "Message Expired" notifications on my watch from Samsung Messages. I've tried disabling Samsung Messages on my phone, as well as disabled notifications to my watch from that app. I've reset my watch again, and I still have this issue. It is common to the watch only. Phone doesn't notify me of new texts from Samsung Messages.
