sos screen turns on randomly
After going swimming with my Series 6 Apple Watch, the Emergency SoS screen has started to turn on randomly, or with wrist movement, and in some case actually starts a 911 call. I've disabled both the Hold-Side-Button-to-Dial and the Fall-Detection features. I've unpaired and paired the iPhone and watch several times. I've erased and reset the watch. None of these efforts have solved the problem. Any suggestions as to what is going on and how to solve the issue?
