SpO2 app is installed but Fitbit app doesn't find it

[Jaelkay]

Since the last App update (5 days ago), my Charge 6 is not recording SPO2. 

I have restarted my FitBit, but the problem continues.

I have the same problem and according to your reply this has been going on since April and it is now almost June. When is this going to be fixed?

On my Sense 2, I continue to get the message that it's not installed and
then that it's not available. However, I get readings most, but not all
days. Weird....
