My calories burnt on my Android Fitbit app have suddenly recalculated. They were once showing a reasonably accurate picture but something has happened where the previous days until 4 days ago have recalculated down. For example on one day, I accumulated 20,000 steps and 9 miles, and this was showing as 3,300 calories burnt, this has now recalculated to 2,113 burnt. I seem to have lost over a 1,000 calories a day, any idea how it can be returned?
