We have a few Google TVs running a Single App Kiosk policy. One test TV suddenly exited the app and started showing the default Google TV home screen with movie recommendations. The device still appeared normal in Hexnode and the policy showed kiosk as enabled, but the TV was clearly not locked into the app. A remote restart did not bring it back into kiosk mode. What is the best way to force the kiosk policy again and monitor this so it does not happen unnoticed on remote TVs?
