Hope someone can help, I upgraded to an iPhone X and Apple Watch series 4 and gave my original Apple Watch to my boyfriend and he’s using it on his iCloud account, and I had an Phone SE, i made sure to remove my iCloud data from the phone, I can see my friends activity on the activity app but cannot see there activity on the Apple Watch iPhone activity app, also they can’t see my activity I just show as 0 and I’m not getting any friend notifications. When I go onto myself on the sharing tab it says “you may also be sharing activity from another device signed into your iCloud account” I’ve checked my iCloud account and the only devices are my iPhone, MacBook and series 4 Apple Watch. I’ve tried signing in and out of iCloud and unpaired the watch, contacted Apple and they’re getting the “engineers” to look at it, can anyone help?
