Pixel Watch stopped giving sleep score

[Tw26]

Hi there,

My new pixel watch captured sleep with no problem the first two nights by itself, including a short nap and gave a sleep score and detailed breakdown of sleep stages. The last two nights though it hasn't. Two nights ago it captured sleep but didn't give a sleep score or stage breakdown. Last night I manually started and stopped the sleep tracking and it's telling me a slept for the time between the manual logs but has 0 hours slept. Any ideas why? I'm wearing it exactly the same as I did the first two night when it worked and I made sure it was fully charged before bed.

At least with the Fitbit models, it is best not to manually start and stop sleep tracking; just let it figure it out by itself.  That was there primarily for models before heart rate tracking, and can also be used to track for naps of less than an hour, which will not get auto-detected.  In fact using "begin sleep now" can interfere with detecting sleep stages.  Some nights you jut don't get sleep stages and sleep score, but instead just get sleep time, awake, restless, times for whatever reason, perhaps couldn't get continuous heart reading throughout the night from watch slipping on wrist or such.

Thanks, I'll try just letting it do it normally and see if that fixes it.
