ive had watch for a few weeks, I've noticed the past few days in the morning While working which I do some walking around in a few stores I'm a sales rep my exercise ring was like 43mins. Today I decided to Calibrate watch for the 1st time went on a 10min run then a 10min walk I'll do the same tomorrow to hit those 20min minumum to calibrate. So I hit outdoor run ran for 10mins, then I hit outdoor walk for 10 mins. So when I go into house I noticed my excerise ring only says 11 mins? Where's the other 9.
