I've had this problem for a couple weeks now. Basically, once I read an iMessage or text on my MacBook or iPhone, the message does not disappear from my Watch notifications. The Watch will also continue to notify me of incoming messages that I've already read about 10-15 seconds later. This only happens for message notifications. It's like the Watch isn't syncing up with my messages. Has this happened to anyone else? Any fix short of doing a complete reset? Thanks!
