Versa 4 won't track my sleep data

[Ninjagranny]

No accurate sleep recorded for three days and yup, yet again no SP02. Come on Fitbit this is getting boring and of course, upsetting.

Hi there, @Ninjagranny. Thanks for stopping by in the Fitbit Community Forums and the details provided in your post about the issue with your Versa 4. I understand how you must be feeling. 

If you're not receiving sleep stages, 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?

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. 

As for the health metrics, please take into consideration the following information in order to get your health metrics data:

• Wear your device for at least 1 full day (during the day and to sleep at night). Check your stats after you wake up in the morning. Note: skin temperature requires 3 nights of data.
• Make sure the back of your device is in contact with your skin. The band should be snug but not constricting. If you experience any discomfort, loosen the band, and if it persists give your wrist a break by taking it off.
• Most metrics require at least 3 hours of quality sleep. If you move a lot during your sleep or the sleep session is too short, you might not get a reading.
• To track your blood oxygen saturation, confirm you have an SpO2 clock face installed. For more information, see How do I track blood oxygen saturation (SpO2) with my Fitbit device?

Having been a Fitbit user for, more than eight years, starting with my faithful Flex, it is so sad what seems to be happening now

And AGAIN. Such repetitive behaviour. Certainly doesn’t enhance my recovery.
