The message Guided Access is not available. Contact your administrator. is displayed after distributing a Single App Mode profile.
This occurs when the app targeted by Single App is not installed on the device.
Check whether the target app is assigned to the template.
If the target app is a VPP app, assigning the app license can take up to 5 minutes. Therefore, if the app and the profile are applied at the same time,
the Single App profile is always applied before the app is installed, and this problem occurs.
When the target app finishes installing, the message disappears and the device displays Single App Mode normally.
You can also prevent this problem by assigning the Single App Mode profile to the template after the target app has finished installing.
Consider the procedure that suits your operation.
