Estimated oxygen variation graph is empty.

I saw and enjoyed the new function appearing in the app after an update about a week ago. However, after have seen it working for 1 day, the graph now stays empty. How can I get this to work again?

It's not a premium feature! I rebooted my charge 3 in settings on the
device. My graph has worked fine ever since. Maybe a glitch from the last
update that needs a reboot. I'm not a premium member.

Rebooting the fit bit worked! Swipe right, go to settings, then to about,
then reboot device

Thank you for your advice; but can you tell me where I swipe right and find settings?
🙄 I knew how to reboot my Charge 2 but my new Charge 3 has me stumped.

I had this happen after an iOS update. Rebooted the charge 4 watch and it is working again. Had tried reinstalling the app, restarting the phone with no result. Reboot the watch from the Settings screen, scroll down to About and scroll down the restart. Good luck.

I think I'm gonna return if because of that. Basic function like find the phone as well.

I confirm the reboot is working for Charge 4 too. Here's my short history:

• Wednesday: I bought the Charge 4. It asked for a firmware update, I did it and restarted the device. In the night it recorded the oxygen variation
• Thursday: it asked for a second update, I did it BUT I didn't restart the device. It didn't record oxygen variation for 2 nights
• Saturday: I restarted the Charge 4
• Sunday: from the last night it started to record oxygen variation again

Note: I am not a premium user.

Look at the main/clock screen on the device, move your finger left to swipe right 3 screens, Settings is there. Tap settings, scroll down, tap About, scroll down, tap Reboot

Cracked my screen on my charge 3. So upgraded to charge 4. Still no oxygen variation, but my husbands charge 3 still shows the data. 
The biggest question is no one at Fitbit responding to the reasons for this!!!!

Same problem. Lost oxygen variation information on my Versa-2 device. Worked for me after the restart. Thank you for your help.

I've also lost the EOV graph since 13 september. I have an Android phone and the last update was on the 10th (don't know if it's related to that). On the 19th the graph came back again for one day and then it was gone again. So I don't see the data anymore. I will try to reboot as suggested here. fingers crossed.

That worked for me with my versa 2 after trying for days to get it to work. Thanks!

Glad to hear. Thankyou for the update.
