Unable to get past update ‘watchOS 8.7.1’
I recently received an Apple Watch Series 3 from a relative who was the previous owner of said watch. When I tried to pair the watch to my phone (iPhone XR updated to iOS 16) I discovered that the watch needed to update to 8.7.1. I tried this, and after taking about an hour to complete the update, it did it again. This continued a few times. I tried restarting the watch (one of the limited things I can do with it due to the fact it is not set up yet) and also tried restarting my iPhone. It has been 2 days of trying this repeated process now. I have also fully backed up my iPhone as that was suggested by another forum. If anyone has any advice as to how I can get past this issue, it would be greatly appreciated.
