I just got my charge 6 and noticed that there's no SpO2 reading inside the app. While looking into the detail page, there's a note asking me to install the SpO2 App and if I click on it, I'm linked to SpO2 tracker app that's designated for sense 2.
This is what I see when I go to learn more:
If I reinstall the preinstalled SpO2 App, the reading shows up. This is the 2nd day it's acting like that. Any Idea why this is happening?

I'm having the same issue with my Sense 2 after the 3.39 & 3.40 updates. I 've also uninstalled/reinstalled the SpO2 app and the Fitbit app. So much for bug fixes and performance improvements.....

Hello @matt_tang & @mhouse
This help page has the steps to install apps on your Fitbit (<-- click link). Go to the Gallery in the Fitbit app should give you the correct SpO2 app for your device.

thanks @RiekoC
Already did that, twice - including deleting the app and resetting my watch, and the app tile and watch say I need to install the app. The app says it's installed and is actually recording data.

@RiekoC I'm an iOS user, just updated to 4.40. Just a side note, 4.40 is on my iPhone which is my sync device. My iPad has not updated to 4.40 yet (still 4.39) and the data is correct. Is there a way to roll back the 4.40 update?

@Fujisan54 the language on the Fitbit is based on your location and not the app on your phone. Just tap on your profile picture located on the top right of the app. Go under Fitbit settings, then date, time & unit. There you can manually set your location and time. I noticed that as I switched from UK to automatic detect, it turned into German since I am in Germany. I hope this helps

@matt_tang Thank you. I had already checked all that but still wouldn't change. Deleted the main app and reinstalled and that worked for the language. Still no luck on the Sp02 though!

Hi everyone! @Fujisan54, @matt_tang and @leanne275 It's good to see you around.
Thanks for your continued feedback and efforts on this matter. While our team investigates this situation, I'd like to suggest the following steps to see if it helps to get your SpO2 readings on the Fitbit app:
- Check on your phone if you are using a VPN; if you do, turn it off while troubleshooting the Fitbit app.
- If you are using Wi-Fi, switch it to mobile data or vice versa.
- Check if the SpO2 app is installed and all permissions are enabled. If you have a Smartwatch, try using a SpO2 clock face such as Signature.
- Wear your Fitbit device at night and sync once you're awake to check your details.
Keep me posted on the outcome.

@LizzyFitbit Uodate. I have noticed that the Sp0 reading on my fitbit is showing but app still says not available. However on the health metrics tab it eventually shows up a day or two late if I look at the last week.

Done them all, SpO2 reading comes later. On the SpO2 page it still show no app installed. And it is still leading to SpO2 tracker app for sense 2. Doesn't the app know I am wearing charge 6?

SPO2 has been working on my Charge 6 for almost a year. Stopped working today - need to install app - app not available for your device - reset and updated firmware on Charg 6 - same message. Very disappointing............... first the 'stairs app' is removed without being made obvious; only found out after upgrading to Charge 6 from 4. Now SPO2 not available - no point me having a Fitbit if this happens as I only use it to monitor health metrics.

Still not working on my Android phone this morning - still showing just 4 health metrics and asking for the app to be installed for SPO2 - then saying 'app not available or compatible with your device'. HOWEVER........ when I use the fitbit app on my iPad, the SPO2 value appears as normal and has been recorded for the days when it was missing from my phone.

I have exactly the same problem and tried all the steps, repeatedly but still no improvement. Additionally my charge 6 won't sync every time, all of this since the last upgrade. Everything was fine, now it isn't. I pay for premium and cannot get all the benefits because of the faults in the firmware/software/app.
Thinking of switching to something else.
