Apologies if there's already a thread on this, but I'm having a problem with a new MacBook Air. It is our first computer enrolled in DEP. We have several App Store apps in Self Service that were purchased through VPP. On the computer in question, when the user tries to install eg Slack from Self Service, the install fails and the App Store opens, requiring an Apple ID to complete the install.
I mention DEP because it seems to be the only thing unique about this computer. I do not have this problem with other users on the same OS (10.13.2). Any help would be appreciated. Thank you.
