Pairing new Apple Watch Ultra
Having just upgraded to the Ultra watch, it arrived today. I unpaired my previous watch, selected Start Pairing on the iPhone and scanned the new Ultra. However, after about 30 secs a brief error message flashes and the phone switches to Unpairing Apple Watch and then takes me back to the beginning. After several attempts, I managed to screenshot the error message as it flashes up and I have included below.
Frustratingly, if I select the upgrade option during pairing, the same error occurs.
