I am getting this error when scoping apps to certain devices:
App Installation - Sign in to iTunes to allow jss.xx.com to manage and install apps.
The behaviour consistently affects one group of iPads but not another
The apps are scoped to devices.
App licences are assigned.
The sToken has been updated.
An alternative VPP source has been tried - same result
The only config profiles on the device are for WiFi.
The same apps push out to other devices just fine.
What could be the issue with these particular devices?
