Got a Series 6 40mm GPS Apple Watch that died about a day after the watchOS 7.6.1 update was automatically installed. Not to imply that the update itself had anything to do with it, but it stopped charging at some point after that, and the battery must've ran down. Have tried force restarting and would see the lightning bolt turn red, then turn green to show it's charging, watch gets warm, then lightning bolt turns red again. Watch was less than 6 months old, and Apple is sending me a box for repair. Am curious to see if others had similar issues.
