Update (2/25): Chrome OS 72.0.3626.177 is now supported. Original Post (2/13) Urgent: Please delay any device updates to Chrome v72 on Chromebooks as it will create an issue for students when logging into their testing session and they will be unable to start/resume their test. As a reminder, automatic operating system updates should be deactivated on all devices. AIR is working closely with Google to address the issue in v72 that prevents AIR from supporting it for online testing.
