I'm having trouble installing a few apps to specific devices. I've gotten the app in the App Catalog with no problems. I distributed the app to a specific device and told the app to install automatically, but it just shows as pending. I tried installing the app from the App Catalog and I get a message stating that the Apple account can't be used to make purchases. The app doesn't have any ability to make purchases within it, so this is confusing. The device shows the app as installing and then just sort of fizzles out and it doesn't install. I'm very new to MaaS360, but I have no idea how to fix this issue and proceed. Any help would be greatly appreciated.
