My activity is now being poorly recognized by my watch.
Specifically, the excercise isn't being tracked correctly.
Like, if I do fairly viigourous excercise for 35 or so minutes, the green ring only thinks I have excercised for 6 minutes.
This is since I updated to the current watchOS.
Oh, and I forgot to add that the back of my watch is CLEAN, and that the other rings are tracking correctly.
