SpO2 disappeared since app update (Charge 4)

[CZStover]

After updating my app to version 3.2 earlier today, SpO2 tracking is no longer visible on the sleep screen.  Tracking had been working without issue and being reported after each night's sleep since receiving my Charge 4 (and the required FW update).  Today after updating the iOS app, even previous day's tracking is gone.  Anyone else experiencing this?

Mysteriously, my chart and data reappeared this morning. The only change I made was to reboot my Charge 4 several times yesterday because I have been having issues syncing to the app.

Update: I can see my EOV now.

Just checked mine and it’s mysteriously reappeared, as has all the data for the days it wasn’t working. No software update or reboot, so assume it was FitBit doing something on their servers.

This is not working for my ionic now. Any update from Fitbit to explain why?

The last version update to 3.29 resolved this problem for me.

The new Google chump owners probably did this on purpose to try and get you to buy premium! I un-installed and installed an older version and my graph is back! (v3.26.1)

I noticed that this has started happening again, since the last app update. Same thing that was happening last year.

No data starting the day after the update. No longer visible on my charge 4 tracker either

I'm running Android 10 on a Samsung S9, same symptoms; skin temperature, breathing and heart rate working mostly OK overnight but no PsO2 for over a week since last update and "Learn More" link has gone from the SpO2 section also,

Same Issue and I did a hard reset of my Charge 4 and still nothing until
about 3 days later if started to shoe the Sp02 again and has worked every
since.
