Logged exercise, no credit for exercise on my daily move. I calibrated it and I still get no credit. I cant believe that it would have a failure on one of its main features. I get credit for standing and calories but not on the exercise recording. Is my watch bad? Yesterday I had 3 logged workouts and ended up getting 19 minutes of credit at random times other than the logged workouts. I think its just going random and not really doing anything at this point. Thoughts?
