In the last week, in Messages, some (not all) of my texts show a phone number and not their name. They are still in my contacts though. I have google'd and tried some of the fixes I found (turn off iMessage, turn it back on. turn off SMS, turn it back on. Reboot. Change short name in contacts to off. Etc.) I also just got an Apple Watch last week which is around the time this started intermittently as well, but at first I just noticed it on the watch and now its both. And seems to be getting worse, more names are turning into numbers. I am not sure if this is IOS 11 problem (my best guess?) or my new Apple Watch.... Help!
