I had an Apple Watch recently but returned it. I definitely unpaired it and my apple watch shows no paired watch. I just upgraded to the new beta 9.3. As soon as it booted after installing the beta I got a pop up saying imessage is being used on a new apple watch, or something to that affect. Is this most likely a glitch or do I have something to be concerned about? Is there anywhere where I can see which devices are tied to my apple ID? Under my apple profile I only see my phone but I don't think that's where I need to look. I'm using a 6s Plus on T-Mobile.
