I have a similar issue. It says “You earned this award for your longest daily Move streak. 1,361 days, ending 9/25/22 (today). Your current streak is 1,363 days” and I noticed it stopped awarding 2 days ago. I hope it’s a temporary glitch since we have long streaks! Congrats on 1,901 days!! That’s impressive.
When I looked on the web, I found articles in the past where a similar thing happened but I don’t see a solution. I tried upgrading to the latest iOS update 16.0.2 but that didn’t fix it for me. I’m getting a new watch soon so maybe that will fix it? I don’t see a watchOS update associated with 16.0.2 though. It still says watchOS 9 is the latest.
