July 27 feedback sent 3:10pm EDT same issue. See screenshot.

Sign-in error notification.

Two things I can think of that happened before turning off the chromebook last night. This is the first sign-in.

1. turned off "smart lock" last night 
2. updated to Version 52.0.2743.85 (64-bit)
Platform 8350.60.0 (Official Build) stable-channel auron_yuna
Firmware Google_Auron_yuna.6301.59.8

Clicked on sign-in notification to sign-in again. 

It asked for 2 step verification as if signing in from an unknown device even though this chromebook is trusted.

Had to sign in to bugs.chromium.org again.
Had to sign in to checker plus for gmail extension again.
