I’ve had this issue on and off for the last couple years and it’s still driving me crazy. The messages on my Apple Watch 6 show 99+ notifications even though I do not have any unread messages on my iPhone. I have the mirror my iPhone enabled, have tried setting my watch up as a brand new watch, and have even upgraded from a 4, to 5 to the 6 and still have the same issue. Is there anyway I can get this to show an accurate unread message count on my Apple Watch?
