I have two apple watches, a series 2 and a series one, that i swap out occasionally depending on the day/activity. every day when i put on one of my watches, regardless of which one i'm wearing, imessage never works on my watch. i have to turn off imessage and switch it back on every day? has anyone else had this issue? has anyone had a fix for this? any suggestions? i've factory reset both watches and it's done nothing
