I have 6 iPads (9th Gen) that are in single app Kiosk mode using the PropioOne app (a language translation service app) that are losing WiFi connection.  These devices are not used regularly. The devices get an error on the screen saying "Guided access app not available, contact your system administrator" and the devices are essentially bricked.  The screen will not let me enter the passcode, the touch is unresponsive, even after multiple reboots it will not connect to network or respond to touch.  The only way I can get the devices to work is to restore and start over.    I have manually put each device into single app mode for PropioOne. Here is the profile settings:       The only work around I have found is to have the device displays never turn off.  Does anyone have any ideas on why this is happening?  I have other devices in single app kiosk mode with no issues but they are used all the time.   Thanks! ...
