The first method you could try is to fix all the possible system issues with iMyFone Fixppo.
This is an ongoing issue and I don't think I've actually seen it figured out yet. Fix iPhone Ghost Message using iOS Repair Tool. I've only been messing with it for a couple hours, but have sent texts back and forth with people on sms texts and iMessage going both ways and checking my phone has marked it read on my watch and vice versa. This will not erase your account setup (you will need to setup passcode and faceid again) or text messages,emails or apps, photos, etc., but it will erase settings pertaining to WiFi, your background customization, and access for apps to cellular data. Second thing (This seems to have fixed it for me) - On your phone, go to Settings -> General -> Reset and "Reset All Settings".
#IPHONE 7 MARK TEXT MESSAGE UNREAD SOFTWARE#
Apple announced that its latest iPhone software will let you edit and unsend iMessages. Some people do this after receiving spoof phone calls from their own number. Apple on Monday announced an edit feature for iMessage in iOS 16. First thing (I did not have this problem, but support suggested it) - Check to make sure you didn't block your own phone number. I followed all kinds of suggestions, up to resetting the watch to factory and setting it up as a new watch (no restore from backup) to the new phone.still, the issue happened. However, when I got the new phone I paired to the watch no problem. I don't recall if I ever unpaired the watch before resetting that the factory. I previously had and Apple iPhone X, then moved to an XS Max. I think this might be solved for me after spending about an hour with Apple in this. I specifically signed up to comment on this thread as this issue has been a major pain in rear.
