What has happened to the estimated oxygen saturation graph in the sleep app on my Charge 3? I have lung problems and this graph is very important to me. It has vanished.
It's come back again this morning on my Charge 3. Just as well, as oxygen-wise I had a poor night. Explains the thick head. Hope yours has come back too, now. Lisa.
Same here for my Versa post-update. I am new to Fitbit and was hoping to use the data to check in with my doctor - some nights I was fine, but others, my levels were elevated at the start of sleep. Having long term data would be helpful.
Hopefully yours will come back as mine did. If not, message Customer Services and ask if there is something you or they can do to get that part of the app back. All the best.
