I have the same problem. Updated to 3.8.2 and now all tracking (including sleep) is off by 5 hours? I go to sleep at 11:00 PM and it shows tracking data starting at 6PM? Also, since tracking time is off, I never get the Pebble steps and points to match the iOS Misfit app steps and points... I tried to go back to previous firmware version with a factory reset and it says the original Pebble app is not comparable. I have tried re-installing everything several times and same problem.
