Hi! For the longest time I had a Series 3 Nike paired with my iPhone 11 Pro Max, and I had no problem with the watch or the phone. When Series 6 came out, I decided to upgrade to a new watch. I received it in the mail yesterday and connected it without any problems. For the rest of the evening, I wandered around with the new features and dials. When I woke up this morning, the watch did not connect to my phone. I tried to open the apple watch app and it simply would not open. I contacted support from Apple, and they asked me to turn off both the watch and the phone, to delete both the old watch and the new watch, and finally delete the contents of the phone and restore it with a backup. Nothing worked. I’m not even able to pair my watch again because the Apple Watch app still will not start. I can not even delete and reinstall the app, since it tells me that I still have a watch paired when I do not.
