Charge 3 isn't registering sleep

[CrysMD]

I've had my Charge 3 for a few weeks and it hasn't tracked my sleep properly one night. Why is this a known issue that Fitbit hasn't solved in over a year of the product being out?

It's great to see you here, @CrysMD.

If your Charge 3 isn't registering your sleep accurately, I recommend trying the following:

1. Make sure to not take off your tracker during the night.
2. Do you remember being awake during the night? If yes, that solves it! Keep in mind that if your tracker will detect if you are awake and will stop the sleep tracking process. If no, proceed to step three.
3. Restart the tracker. See instructions in the help article: How do I restart my Fitbit device?.
4. Confirm that the tracker is snug on your wrist (with an HR tracker, the lights shouldn't be visible).
5. Try sleeping with the tracker on your non-dominant hand.
6. If the setting was set to sensitive, please switch it to normal. 
7. If steps 1-6 do not solve the issue, I suggest manually editing the sleep log to reflect the time slept. See instructions in the article: How do I change my sleep history?.​

Let me know the outcome. 🙂
