My apple watch3 is currently version 8.3, and I have been unable to upgrade 8.7.1,
I have a Apple Watch Series 3 GPS + Cellular,It won't work with my ios16 device because it's prompted to upgrade, but it gets stuck on the installation screen and doesn't move.
I paired it with an ios15 phone and it works fine, but still can't upgrade,It is also stuck on the installation page.I made sure the WiFi was connected,
What could be the problem? Thank you!
