So...I have two Apple Watches: Stainless Steel and Space Black Stainless Steel, both with the links bracelet. I went to update them last night, choosing the Stainless Steel to update first. The update downloaded to the watch, and went through the installation and then restarted. When it restarted, it got stuck on the Apple logo. The screen never turns off. It's always on the Apple logo, even when off the charger. Restarting the Apple Watch produces the same result. I dropped it off at the Apple Store this morning to be sent out for repair, but wondering if anyone else had update issues. Now I'm a little gun shy about updating the Space Black watch, at least until I get the Stainless Steel back so I have a backup.
