Hi Jonathan, I followed your instructions and the pairing issue now seems to be fixed, but I have lost 9 days of workout data plus all my apple pay card details (at least I can reconfigure those). I had the same issues as the others in this thread, so I unpaired the watch and phone, which looked as if it had completed successfully but afterwards the watch was unpaired but the phone was not. I was encouraged that the phone had, at least, taken a backup of my watch and after much hesitation I reset my watch to factory settings and set it up again from scratch, since unpairing it had turned it into nothing more than a big single-function device for telling the time. Some of the watch configuration is restored from the backup, but not all of it, e.g. the workout data for 9 days has been lost. It has taken up a couple of hours of my time to try the various solutions and now I still have to reconfigure Apple Pay on the watch. I wonder if I should have waited for a software fix, since this all happened after the last one. I have had a policy of applying updates immediately, but now I wonder if I should wait a week first to see if they are going to wreck my data 😟
Thanks anyway for the advice, at least the watch is now working again.
