Versa 2 doesn't track my sleep and SpO2 accurately

[SunsetRunner]

Sleep traking has been a problem for many for years but nothing has been done to fix it. In fact any changes that have been done to sleep tracking have been a retrograde step. A one time it was possible  to adjust the sleep times manually and get a more accurate result. You can still adjust the times but the  result now isn't what you'd expect. The sad thing was the data was there in the past and the affected user community were willing assist infixing the interpretation. That offer was ignored and tinkering by the dev teams lost the access to the data.

So if you want SPO2 data and your sleep tracking doesn't work for you be prepared to be dissapointed.

Hello there @SunsetRunner, welcome to the Community Forums. We acknowledge the limitation we have on our part particularly on what you have experienced. We‘re taking into consideration your comments and sentiments with regards to our products and services.

If you're not getting your sleep data accurately, please see Why don't I see sleep stages today? 

About SpO2, if you see dashed lines on the clock face, a message that the SpO2 data couldn’t be read, or missing data in the Health Metrics tile in the Fitbit app on your phone, keep in mind the following:

• Your device doesn’t retroactively measure your SpO2 values. When you start using Fitbit SpO2, you’ll see dashed lines until after your next sleep session.
• You must get at least 3 hours of quality sleep. Data is only collected when you’re still. If you move a lot during your sleep or the sleep session is too short, you might not get SpO2 data.
• Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using an SpO2 clock face or app.
• You must sync your Fitbit device with the Fitbit app before the clock shows your SpO2 data. Note that it may take around an hour for your SpO2 values to appear after you sync your device. For troubleshooting syncing, see Why won't my Fitbit device sync?
• Turning off any SpO2 clock face or app permissions can cause the feature to stop functioning. For instructions on adjusting permissions, see How do I install and manage apps on my Fitbit device?
• Your Fitbit device must be able to consistently track your SpO2 data:
  • Wear your device slightly higher on your wrist.
  • Make sure your device is in contact with your skin.
  • Your device should be snug but not constricting.
  • Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.
