I hadn't used it for a week, and it seems the app got updated in the meantime, as sleep metrics look different - oxygen variation is gone. It is also slow as a sedated snail, so I would need a new phone to use it all.

Hey there,
I just checked my app and I can see the 02 variation in the sleep section as an overview text link right under the sleep graphs and when I click it, I see the line graph of the variation.
Maybe delete your Fitbit app cache and restart the app.
Best regards

Hello @partugyan
By any chance, are you using a Pixel Watch and recently installed the Pixel Watch March update?
After I installed the Pixel Watch update, I stopped seeing data for SpO2 and skin temp variation. A fellow PE told me to check the Fitbit permissions on my watch. It turned out that the March update turn off the health & wellness permissions for the Fitbit app on the watch. I started getting data again after I turned the permissions back on.

All mine shows is sleeping heart rate. No more O2 variation

Hello @001Joe
Did you check the permissions for the Fitbit app on your Pixel Watch? Many of us have had to turn the permissions back on after installing the March Pixel Watch update.

Yes, I've allowed permissions.
I'm usually a Charge 6. The graph shows in the public app but not in the Public Preview App. I've sent feedback to Fitbit/Google.
