Updated 9/14/20: We have identified the issue and have released a patch to the Arreya client application that works around the issue caused by the Chrome OS upgrade from 84 to 85. Client devices should automatically pick up the update and begin displaying content again.
You may need to reboot your devices if they are stuck in the reboot loop, or stuck at a white or black screen. This can be done remotely through the Google Admin console or by physically powering off the device and turning it back on. If you are still having issues, please contact email@example.com for help.
In the second week of September, 2020, some clients and other Chrome OS users began reporting that their Chrome devices in Single App Kiosk Mode began showing an issue that prevented the kiosk app from launching. The issue appears to occur after the device upgrades from Chrome OS version 84 to 85.
After a reboot, the Chrome device will display the Chrome boot screen, followed by the white Arreya screen during the kiosk launch step. From here, the screen will remain at a blank white screen, or cycle between a black screen and a white screen and never advance to the kiosk application.
At the moment, there is no identified cause. We will update this article as soon as more information is available.
We are recommending that our clients pin their Kiosk devices to Chrome version 84.* This can be done in the Google Admin console, under Devices > Chrome > Device Settings. Under the Device update settings heading, set the “Restrict Google Chrome version to at most” to 84.*
We will continue to update this article with more information as it becomes available.
