i would like to say that I am able to use the device normally on O DP2, I tried rolling back because Netflix was failing - but I think Netflix updated their app and it no longer fails. I will be on the DP2 till I find it totally unstable for regular use.

Thanks for the information in comment #3. The engineering team has fixed this issue, by providing a modified build for OTAs. All users should now be able to successfully downgrade to Android N on Pixel C devices. If your device is not receiving the downgrade OTAs, enroll and unenroll once more in the beta program.
