Hi, Just wanted to let you know I got the tracker working again. I got on the Fitbit site and was told to plug my Fitbit into the charger and hold the button down for 10 to 12 seconds let up and push it again and that will reset it. It worked. It hadn't recorded anything for over a week and everything came back. It said I was connected on Spark but it took awhile for it to sync but finally did. I have a Fitbit One..... Hope that helps. Have a good evening!
