Yes, I am generally ok, (apart from being behind by one day), but my wife's Sense is hopeless with SpO2. She gets a reading on the watch about 1/2 the time, and it syncs to app about 1 day in 7 if lucky. Rebooting the watch helps for a couple of days - sometimes. Uninstall/reinstall of spo2 watch face is also suggested but doesnt do a thing. At moment, it is reading on the watch after reboot but hasnt synced to app for a while.
Fitbit give us the "we are sorry you are having a problem and we are working to fix it" (since forever if you look back at complaints on the forum). Evidence would suggest that Fitbit have simply abandoned Sense so I wouldnt hold out much hope.
