I just finally received my watch this evening (after having to work all day long knowing it was at home!) and I noticed that with the glance for weather too.
My weather was stuck earlier this evening (not updating the hourly views) but seems to have resolved itself. That was the first time.
I've never had the rings freeze (that I noticed)
Do you mean the weather glance or weather app?
Im having the same issue. All my glances wont refresh. A quick restart of the phone and the watch fixes the problem when it does happen. So far 3 times for me.
