I've been having issues with my Series 2 (42mm) keeping in sync with the iPhone. (Both running latest Betas). (10.3 [14E5239e] and WatchOS 3.2 [14V5214d]). I have to watches, an original sport and the series 2. I figured I could fix the problems by un-pairing and re-pairing, like I've done with GA code before. Since unpariing the Series 2, I have not been able to re-pair it with the iPhone.
I start to try tell it to setup as a new watch, and asks about right or left handed, and then it fails saying it can't pair.
if I try and tell it to restore from a backup, I get the same message:
Pairing Failed - Your Apple Watch couldn't Paor with your iPhone. Start Over
I seem to be stuck at this point. Any suggestion? Do I need to back off of the iOS 10.3 beta? I've not tried that step yet.
