I put up a post 12 weeks ago re syncing issues, and got a response from garmin admin a week or so ago that they are working on this, well hallelujah, about time but a little too late, wake up to be kicked out and it starts as a new unit, no sleep, steps, body battery, watch now asks to use phone gps before starting workout and have to respond on phone to start a workout (never had to before)..... constantly have to plus into pc to get a sync, but still data does not show. I have been more than patient, I am guessing tomorrow a fight begins when I take it back for a refund
