Versa 2 isn't tracking my SpO2 data

[SunsetRunner]

Why does my fitbit Versa 2 give me a - - % SpO2 rating with the message no sleep access underneath it?... I have worn it high up on my arm, a bit tighter than usual, I just recently (yesterday) updated to the latest system.  I gave the spo2 thing all permissio

Hi there, @SunsetRunner. Welcome to the Community Forums. Thanks for making sure you're wearing your Versa 2 as recommended. 

Please bear in mind that after waking up and syncing, it takes about 60 minutes for the SpO2 reading to appear on your Versa 2. 

However, if you see dashed lines on the clock face or SpO2 tile, 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.

Hope this helps.

I have done all the things you mention in your post.  I get a reading for a few days in a row, and then, for no apparent reason, I don't get readings.  Nothing that I can think of has changed.  If I uninstall the app from the watch and then reinstall it, I get a few days of readings, and then the same thing happens. This is becoming very frustrating.  I have asthma and really like the SpO2 feature.  Any suggestions?
