Yesterday my Sense decided I was asleep mid-afternoon while sitting up working on my laptop

[sarcazm]

That isn't the only sleep recording issue I've had either - I needed to correct the time I went to bed last night as well as the time I woke up, as the Sense had me going to sleep while I was watching TV in the living room, going to the bathroom, and also recording steps and logging a late-night snack; it had me waking up after I answered the phone call it put through to me too, moving around, and all of that in deep sleep with no awake minutes. 

I've been having other issues as well, and I made sure my Pixel 4 (not the XL) is a compatible device, so theses shouldn't be issues.  I've reset everything, uninstalled and re-installed the app as well as made sure all the settings should be in good working order and done the same with my watch:

My watch and phone seem to not be able to find each other when I practically have them kissing via Bluetooth, but this morning, even though I definitely had this setting turned off, that phone call came through to my watch (getting it transferred back to my phone was an interesting thing to do while half asleep).  

Also, it gets hung up trying to sync data, and the only way it will do so seems to be manually via me dragging down the hidden header bit at the top of the app when opened.  When it freezes in sync mode it is only the app and syncing process with the watch that seems to do so - no other issues with the phone, and the quickest way to make it stop is to restart my phone (clearing cache and going through the uninstall/reinstall app process doesn't help much yet.  

I should point out that there was an update for the Fitbit App (Version 3.35) that finally came through to my phone yesterday which might be causing a bunch of these issues but I can't be sure.  I would hope, however, an update to fix these bugs as well as other bugs that many are experiencing might be fixed with another software or firmware update soon?

I had a similar experience.

Sense reported that I was sleeping when I took the watch off to take a shower at 5:15PM till I put it back on an hour later.

Then it reported NO sleep from 11:30 PM through 2:30 AM when I woke up.   I was awake for about 30 minutes and then went back to bed.  Sense reported sleep from 3AM till I woke up again at 6:30AM.

Why does it do this? How accurate can it be if it mistakes no heartbeat for sleep time?  How accurate can it be if it misses sleep all together and then what factors are going into SPO2 levels?

thanks
