I also did everything you did, but now my HRV just showed up for today, but missing SPO2. Watch says Can't read SPO2. And App says No Data. (BTW, there was an update that installed yesterday morning for both Fitbit and Sleep as Android.)

Hi @the4as. It's good to see you around.
I've moved your post to this new thread as you're having a different issue with your Sense. Thanks for the troubleshooting steps tried prior to posting. As you may know, your watch can record SpO2 data using the SpO2 App, and then transfer it to the Health Metrics tile after syncing. However, there are certain factors that may prevent your watch from recording this data. If you've not done so, I'd recommend reviewing this help article which explains more about how to track and see this data.
Additionally, because you have an Android phone, please give a try to the following steps:
- On the Fitbit app, tap your profile picture > Sense > Apps.
- Look for SpO2 Tracker and make sure there isn't any pending update.
- On your phone's settings, tap Apps > Fitbit > Storage > Clear Cache.
- Go back one screen, tap Force Stop and reboot your phone.
- Open the Fitbit app and pull down on the screen to force a manual sync.
- Wear your watch slightly higher on your wrist at night and sync it with the Fitbit app once you're awake to check your details.
Hope this helps.

Hi @the4as. It's good to see you here in the forums.
Thanks for your efforts while trying the troubleshooting steps suggested above. Before you mentioned to have performed a reboot and to confirm, may I know if you refer to the restart process? As you may know, our team is aware of an issue with the SpO2 data not appearing in the Health Metrics tile even though it appears on the Sense. This issue seems to be affecting your watch preventing it from recording this data and syncing it to the Fitbit app. I'm sorry for this inconvenience and I'll pass your feedback to our team so they can be informed of the impact to you. Once I have more details from them, I'll update this thread.
