When I complete a workout, the number of zone minutes showing on my watch so not match the number on my app. For example, I completed a 30 minute cardio workout, starting and stopping it using the Workout setting on my FitBit. When I was done, the device recorded the workout lasted 29:54 minutes and earned 53 zone minutes. When I synced my app and opened the workout there, it said the workout lasted 29:54 but only earned 29 zone minutes. It does not seem to be doubling the minutes for vigorous or peak activity. The total activity in the app seems so be correct.
On the flip side, some things that appear in my app don't appear correct on my device at times. For example, I got 6 of 9 hours of steps yesterday and the device only read 2 of 9 at the end of the day.
