Another bummer. And thanks for posting.
This particular Pan may be toast (it’s a long shot someone will come along with a fix that works, but not impossible.)
If you do get another or have others many recommend clearing the decks before updating:
Reboot your phone/tablet.
Power-cycle the camera (plug out/in).
Clear cache in the Wyze app, close and restart it.
Update each cam individually. If it completes successfully, power-cycle the camera, close and reopen the app. Then check performance.
I don’t speak Apple so there may be a few more things others can recommend. Good luck, a9, and sorry for your loss.
