I’ve had my series 4 (cellular) since the beginning of November. Prior to that I had the series 3, which was not cellular. Literally since the day I got the watch, I’ve had to unpair and repair it once a week (no joke) because texting on my watch stops using iMessage and switches over to text. I’ve tried every suggestion I can find to get it to switch back to iMessage without having to unpair and repair, and nothing works. Does anyone having any idea what’s causing this?
