What’s your location in the world? Most reporting so far are ukI spent a good hour or two yesterday eve. with apple support. did everything, unpaired etc. no joy. all Apple suggested was for me to send it in and they'll check it out, or take it back to store for a refund. If it's software I'd rather hold onto it, but doesn't look like this is a large issue for everybody. maybe a few duff watches? weird coincidence these issues all appeared at the same time yesterday though!
