First, spo2 stopped tracking. Now my heart rate & sleep disappear. Yes, I've tried all the lame "fixes" & nothing works. Its been over a month now. Im a 49yr old asthmatic with an Extremely physical job, my fitbit was my means of checking in on my body. After all the shenanigans with fitbit, Im moving on to a brand with more reliability. Sorry fitbit but you have failed me too many times
