I had an Inspire 2 and recently bought an Inspire 3. Just as my Inspire 2 was doing, my Inspire 3 loses its history of Exercise Days. It will end of the week acknowledge the correct number of days but if I review the history of the Exercise Days it will indicate 4 of 7 were completed when I had credit for 7 out of 7. No matter of resetting it or rebooting the Inspire 3 corrects the problem. As I had it with my prior model I have to assume its a flaw in Fitbit that doesn't seem to warrant investigation or repairing.
