Bug using WearOS? Only records formal start and end time, not actual time asleep

Hi,

I’m using Fossil gen 5 with an Android Pixel 3, apps and OS up-to-date. The past few nights I tried activating SaA each time from my watch, but it records the activation beginning and end time as my actual sleep time. Is there something else I need to do?

The phone is in range, but not in my bedroom (I’d rather not keep it near my bed). Does SaA’s Wear app work without the phone in snoring range? Does SaA’s Wear app not detect movement?

Thanks
