PW 3 with Fitbit premium doesn't track my sleep

[Xobat]

My PW3 doesn't track blood oxygen while I am sleeping and doesn't accurately record my sleep time.

It only worked for the first 4 days I had the PW3. This is ridiculous.

Sleep tracking can be affected by how the watch is worn on your wrist.

Try wearing it looser or tighter to see if that helps.  Also try wearing it a little higher on your arm.  I wear mine so that the strap is further up and not resting on my wrist bone and I get readings nearly every night.

Thanks, I will definitely try that.

I find that Fitbit doesn't do a good job of tracking my sleep at all. I also use a third party app, Sleep As Android, which uses the same sensors on my Pixel Watch 3. I tell both apps that I've started and stopped sleeping and almost every night, Fitbit fails to track the first hour or two of my sleep. I add it manually based on the actual sleep time from the Sleep As Android chart. I shouldn't have to add it manually though because:

1) Fitbit should correctly detect my starting sleep time, especially with my telling it that I started sleeping. 

2) Sleep As Android has permission to write to Health Connect and Fitbit has permission to read from Health Connect.
