[Poisons]

In the app dashboard it keeps saying there's no blood oxygen data

 but if I enters the health metrics, the blood oxygen data is there

Hello @Poisons 

I've seen this happen on my app as well. Sometimes, it fixes itself on its own.

When you tap on SpO2 in the Health Metrics tile, do you see your graph with your daily readings & none are missing? If so, that's a good thing. That means your readings are being uploaded to your account on the Fitbit servers, so there's no loss of data.

Although I'm not sure that this will work, you could try clearing the cache for the Fitbit app on your phone, force stop the app, then re-open the app.
