My Fitbit is not tracking zone minutes and sleep consistently. Anything I can do to help this?

Welcome to the Fitbit Community forums, @KareBearGetsFit. 

Thank you for sharing this information about the inconvenience you've been experiencing with your Charge 5. 

These issues you mentioned could potentially be related to a problem with heart rate tracking. Before considering other options, I recommend that you try restarting the device using the three pulse restart method mentioned here below, instead of the restart option found on the Charge 5 itself: 

1. Connect your device to the charging cable. For instructions, see How do I charge my Fitbit device?
2. Press the button located on the flat end of the charger 3 times, pausing for 1 second between presses. Then wait 10 seconds or until the Fitbit logo appears.

In addition, please follow the instructions in this article to improve the accuracy of heart rate information. Regarding the problem to track sleep, please make sure of the following:

• If you slept in a position that prevented your device from getting a consistent heart-rate reading or wore it too loosely. For best results, wear your device as described in this help article.
• If you slept for less than 1 hour for sleep patterns or less than 3 hours for sleep stages.
• If your device’s battery is critically low.

Try adjusting the sleep sensitivity on the Fitbit app and check if you continue to have the same problem. In addition, please wear your device on your non-dominant hand and monitor it for the next few days. In the meantime, for the nights that don't have sleep data, you can manually log your sleep by going to the Fitbit app, tapping on the "+" icon next to the sleep tile > Add Sleep Log and entering your details.
