Versa 4 is not tracking my sleep score

[6915gene]

This morning I did not get a sleep score. It seems that my sleeping heart rate did not sync with the sleep algorithm.  I looked at the "Heart" section of the Dashboard and the data had been synced there.  My phone is an Apple iPhone, using Fitbit Version 210.26.  I rebooted the watch, the phone and the application to no avail.  Any suggestions on a fix?

Do you mean that you have been getting sleep scores all the other nights?
Did you get sleep stages but just not a score?

Hi there, @6915gene. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that your Versa 4 is not tracking your sleep score. I understand your concern. @JohnnyRow Thanks for trying to help! 

Keep in mind that you must see sleep stages in order to see your sleep score information. Please swipe left on the Sleep Score graph, here you can see information about your weekly sleep average and sleep duration. To get more detailed information, see What's sleep score in the Fitbit app?

With that in mind, 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.
