Thanks. Yes we checked all of that but still issue is recurring. Working with Apple Support and engineering and awaiting next steps. I’m up date on both the latest iPhone and watch iOS as of this afternoon. I had gone to the Apple Store last week which initiated the replacement watch.

If Apple is replacing the watch, I wouldn't worry too much about this one.
