My Fitbit Charge HR is wonderful; however, it hasn't been tracking my steps correctly on the app the past few weeks. Even when I sync it, the app will still show thousand of steps less than I actually got. Last week, I got over 10,000 steps one day, and it said I got 3,000. It's making me last on my friends list and it won't give me badges even when I earn them. Thank you in advance!
