Question SpO2 Monitoring doesnt work in sleep

[Jasher]

Hi guys,
I cannot make the oxygen monitoring work during sleep. I updated the app and I have enabled "Sleep breathing quality monitoring" in settings. But it works for manual measurement. I am attaching screenshot of the data I see.

I noticed that when I run the manual measurement there is a red glow inder the band and I saw this red glow during the night.

It is not SpO2. It is sleep breathing quality.
