"Import from VPP" has greyed out and is unclick able. At first I thought I might of exceeded the limit of how many App you can import (39) so decided to delete one. - Didn't change a thing however now another App down.
I then checked the Expiration of the VPP token (however this is next year). It successfully synchronised but unable to import my Apps.
I have also downloaded and uploaded the VPP token again hoping this might resolve the issue however this is not the case. Checked on Apple DEP/VPP in case I needed to accept any new terms and conditions however I'm just stuck!
