Sense 2 won't track my sleep data accurately

[BeeDeeW]

Using Sense 2 for 3 weeks after having a Charge 2 thru 5 for 7 years and getting good functionality with sleep tracking. Not with my new Sense. It seems to be OK and registers when I fall asleep but then just stops after a couple of hours. I wear on my non-dominant wrist and have tried both normal and sensitive settings. Last night it stopped at 02:46hrs a.m., the night before at 01:31 hrs a.m. some nights have been fine but about 50% of the time it's not. Everything else is being recorded and it seems the watch thinks I have got up when I'm sleeping fine and wake as normal around 07:00hrs. I have a regular falling asleep time of between 22:30hrs and 23:00hrs. What could be going on and what can I do to make it work as well as the Charges did?

Hi there, @BeeDeeW. Thanks for stopping by in the Fitbit Community Forums and sharing the details about the issue with your Sense 2.

As a first approached, I'd recommend to sync your Fitbit device to the app after waking up. This will help to make sure that all your data is sync properly. 

Also, note that your time asleep is calculated by subtracting your time spent awake and restless from your overall tracked sleep time. For example, if you slept 8 hours but woke up 2 times for 15 minutes each, your time asleep would be 7 hr 30 min.

To learn more about your time asleep in sleep stages, see What should I know about Fitbit sleep stages?

Edit or delete sleep logs in the Fitbit app. For instructions, see How do I add, edit, or delete Fitbit data and activities?
