My wife and I both got Apple Watches, and for iCloud Photo Library reasons, both of our phones use the same iCloud account. Our ability to send each other taps/drawings/heartbeats is completely messed up, likely because of the shared iCloud account. Namely, I'll send something to my wife, and nothing will end up on her watch. She'll send something to me, and it ends up getting sent to her own watch. Our friend will send something to me, it ends up on hers, or sometimes mine, or sometimes both. Anyone else seeing this, or have possible solutions? And no, using separate iCloud accounts won't work, as a shared Photo Library is much more important that sending drawings.
