Pixel 6 Stops Sleep Session

Detailed description of the problem:
Hi, I’m using a Pixel 6 with Polar Verity Sense. I’m also using a Manta Audio Sleep Mask for Lullabies. Lately my sleep session will stop after an hour or two and the app give no indication of a problem… no error message. I sleep with my phone next to my pillow. Wonder if the logs might indicate what the issue may be. This is quite random as well… some nights it’s fine and others it’s not. Thanks
Steps to reproduce:

Version of Sleep as Android:
V 20250308

Hi @Mark_Weiss, could you please send the logs to our support email?
Is the tracking running on the FitBit in the morning? Or where does it stop - on the phone or on the watch?
