Hi there, @Josworld. Welcome to the Community Forums. Thanks for the details provided in your post about the issue with your Charge 3.

I recommend considering the following in order to get sleep stages:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading. The band should feel secure but not too tight. 
• If you used the Begin Sleep Now option in the Fitbit app (instead of simply wearing your device to bed). For more information on automatic sleep tracking, see How do I track my sleep with my Fitbit device?
• If you slept for less than 3 hours.
• If your device’s battery is critically low.

For more information, see What should I know about Fitbit sleep stages?

If the above doesn't work, may I know if you've noticed inconsistencies in your heart rate readings during the day? If so, please see What factors can affect my heart-rate reading on my Fitbit device?
