Versa 2 stopped tracking my sleep data

Ever since the upgrade on 9/18/25, my Versa2 stopped calculating my Sleep data.

Hi there, @PamVersa2. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention. I'm sorry to hear that your Versa 2 has stopped tracking your sleep stages. I understand your concern, I will do my best to help you with this!

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 or wore it too loosely. For best results, wear your device higher on your wrist (about 2-3 finger widths above your wrist bone). 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?

On a side note, I have found that having WiFi turned on on my phone will interfere with syncing of some of the data, sleep is one of those. You may need to wait for a min or two before sync will be successful.
