I have had the same issue when i was charging the watch yesterday nothing would work on the watch at all
just get the message displaying couldn't connect to apple watch.
The only thing that i could do was reset the watch all together and re pair the watch and it seems to have done the trick and working fine with no problems at all.
Since updating to watch os2 it seems i cannot receive any messages to my wrist at all everything is in messages but their is no nice tap saying you have a message to your wrist which was very helpful
when you are out and about places and some one messages you.
i just wish when apple release new os updates that basic things like messages are working that is i think one of the most important things on the watch to be working is messages.
I would of preferred to wait a couple of more weeks for the new os updated then to have this least on the old version that messages were coming through to my wrist with no problems at all.
My point is the problem you are unable to downgrade which i think is completely wrong all together you should be able to have the option to downgrade when you want to not have to be stuck with the same os problem.
At the moment i feel that my watch is 30% useless because i'am not getting the tap to my wrist which
i really enjoy when i get a message.
I have decided the next big update that comes out for the watch i won't be going near it for a least 3 months until other people have had the problems and they have been ironed out.
