Fall Asleep Time Not Recorded and Time Asleep is Incorrect

[Dubdavis]

I have a Charge 3. My sleep reports consistently show that I was just asleep - not awake and then fell asleep (I think that has recorded only 1 time). Plus, it doesn't record the correct time I fell asleep - sometimes it is off by as much as 5 hours.  I restarted the tracker, uninstalled/reinstalled the app., updated the app, switched to sensitive (no improvement) and then back to normal, changed from my non-dominant arm to my dominant arm (no improvement).  Since none of those things worked, I traded trackers with a friend and my tracker recorded her sleep correctly - her tracker did the same thing to me that mine does - suddenly sleeping and the time I fell asleep is incorrect. Also tried wearing the tracker tighter and looser on my arm - no improvement.  Any idea why my charge 3 won't pick up on my sleep time?

mine states it did not record sleep at all, however, when I press the sleep icon in my profile it shows the stats! they appear to be correct but on the fitbit itself it says not recorded!

Mine shows the same info on the tracker, as it does on the app on my phone, as it does online on my dashboard.

I have a fitbit 2. The sleep tracker has gone crazy. One day it said i did 30 minutes aerobic exercise during sleep, but the HR is 65. Then this whole week it says i 2 hours from 9/10 to midnight and thrn from 4 to 6 in the morning, when i was asleep the whole time. I'm about to throw this away.

I have a fitbit3 and it does the same thing... continually says sleep not
recorded but if I go into the sleep stats it gives me them!! not happy with
this device at all

• I had a charge 3 that worked till display stopped.  Had it replaced with charge4.   Total lemon.   Am getting run around from customer service.  This is the only function I wanted the watch got and it doesn’t work.   Suggestions?
