Autonomous Single App mode (ASAM) locks an app when a user signs into it and releases the device when the user signs out of the app. While the app is locked no other features are available.
Once your devices are enrolled in Zoom's mobile device management service (ZDM), or a third party MDM, you can enable ASAM and the Zoom Rooms app will automatically be installed onto your iOS controller. When you launch the Zoom Rooms app on your iPad, it will be in ASAM.
If you experience network issues, the Zoom Rooms app allows you to leave ASAM (protected by passwords) to fix the network issues.
