I have a 42mm Space Grey Apple watch linked to my iPhone 7 (both have the latest iOS updates). I am having a strange issue whereby when I receive an iMessage and I read it on my watch, when I then check the same message on my iPhone, the message conversation still shows the blue dot which signifies the message is unread??! And yesterday, I experienced the same problem but it went one step further: An iMessage came in and I read and replied to it from my watch. 5 minutes later when I checked the thread on my iPhone, the blue dot was STILL showing next to it, even though, when I then went into the message, I could see the reply I gave from my watch????? I'm also seeing random iMessages that don't clear from the Lock Screen on my iPhone, when I dismiss them from my watch?! Ths normally only happens when I receive a picture message - the message comes in and I dismiss it from my watch. After a minute or so, when I check my iPhone, the same message is STILL showing on the Lock Screen of the phone so I have to dismiss it from there as well??! This has only been happening in the past week.....?!?! I wonder whether a 'Unpair from iPhone' process will sort this out, as then I will have the option to pair it again and restore from the back up the watch makes when you unpair it from the phone?! Anyone else experienced anything similar?!
