Hi @DK92123. A warm welcome to the community forums.

Thank you for sharing the inquiry regarding your Versa 4. 

Keep in mind that there are some factors that may prevent your tracker from recording your 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.

If you haven't done so already, please follow the steps listed here below: 

1. Complete a three pulse restart procedure.
1. 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.

Why won't anyone at Fitbit Help or on this community address the issue of the changed algorithm adversely affecting readings? There are several posts in here about this, I spent an hour in a chat with the help desk doing the resetting and reporting I'd tried sensitivity, none of these answers are responsive as to why readings have changed since June 25 (or so) for so many of us.
