Estimated oxygen variation not working

[MadamQ]

I have the box, but nothing has ever been inside it.

I have the same issue. Each morning I have to go to phone settings, select 'Apps & Notifications' then select 'Fitbit' then select 'Storage & Cache'  then select 'Clear Cache'.

My oxygen data from the last night always appears immediately when I do this. Hope that works for you as well. 

----------------------------

For me I have to close the app, open phone settings, select Apps, select Fitbit, select Storage & cache, then l Clear cache. The oxygen graph always shows data when I reopen the app. I have to do this every day to see that data.

Hi Sunset Runner.

I notice you said yours started working. I have a similar problem:  oxygen variation just stopped appearing recently on my Charge 3. Was there something you found helpful?  I appreciate your time

[Jencrna]

I wish there was a magic trick! One day I just notice that it was back. Now it works intermittently.

My Charge 3 stopped showing the oxygen variation on 8/2.  Box is still there but blank.  None of the answers have worked.   Is anyone at Fitbit working on this issue and is there a fix that works?

I tried the cleaning of the sensors with just a soft cloth, placed on the charger and pressed and held the side button until it reset. Was back to normal the next morning 

[CircusandSpande]

What was the problem? I'm having the same issue and can't seem to find any help. 

[Jorday]

Cleaning the back like recommended did the trick for me.  
Someone also suggested after cleaning to plug it into the charger and press the side button to reboot/reset.  I didnt have to do that.  
Good luck.

Wait, so what's the reason that your light wasn't working? Mine (versa 2) has stopped giving me data too!

[Jencrna]

I don’t know. I just did all the stuff people suggested, and it finally came back on.

My Charge3 no longer showing my O2 Chart. Possibly from iPhone update last night?

[NICGuy59]

Perhaps try a reboot on the watch, just in case?

Not sure why an update would cause a communication error, but then, why would something like changing the clock face display shut down oxygen variations?

[AJMROZ]

I don't understand how this is the best answer. It doesn't answer the question at all. ???

[AJMROZ]

How is this the best answer? And why does the thread have to be about only one version? 

[Dave526]

I updated the Fitbit app (Android)  3/31/2021) and no longer see oxygen variation box.

Hello I have a verse 3 I only joined Fitbit yesterday 

My C02 part doesn’t work ?

also I realise I have to open the app to find out thing like how did I sleep as it hasn’t functioned with the watch until I do so ? 
I find this strange as before this watch I had a cheap 40 pound smart watch and I didn’t have to do that. Can you please help me to find a solution to this if there is one

I am experiencing the same issues with my Versa 2 beginning about 1 week ago after working great. No longer getting oxygen readings with the sleep info.  

[stevencj]

Did a forced reset of the watch (holding down the side button until it turns off). The oxygen info came back on my app for today and all the missing days.
