Currently (and the last month) my activity hours are 6am -2pm if I change it up an hour or 2, save and it shows in the app correctly (but will change at some point) but my Chg 6 doesn’t recognize the change. Stays 6-2, frustrating. Have restarted my Fitbit a couple of times but nothing has changed on the hourly activity path.
