Google's bulletin says that Chrome OS version 91.0.4472.165, which was briefly available this week, renders users unable to log in to their devices, essentially bricking them. > Chrome OS automatically downloads updates and switches to the new version after a reboot, so users who reboot their devices are suddenly locked out them. The go-to advice while this broken update is out there is to not reboot.
