I had a broken nights sleep but did not move my Fitbit as far as I’m aware. The first sleep was recorded with all the details. The second sleep it just says couldn’t get a consistent heart rate. If this happened all night or all the time I’d understand maybe it’s just me. But my watch never moves so I don’t understand.
Does anyone have any ideas what might be happening with or if there’s a fault?
