I have a fitbit sense, and while tracking it seems like it’s connecting to the app via Bluetooth (it shows that flashing Blutooth symbol with “Sense” next to it) but it doesn’t seem to be recording heartrate or oxygen, even though I have all those things enabled in Settings>Wearables. I’ve tried ticking all the options and also only just the Bluetooth ones, and nothing seems to be working. This is very important to me because I’m desperate to use the breath rate alarm. I suspect I have severe sleep apnea and this is the only app I’ve found with a feature like this.
