Install internal Apps via JAMF

New Contributor

Hi, guys,
I use the Jamf School Manager. As far as I can see, everything works fine, but the one thing that doesn't work is installing "internal applications" via Jamf. As soon as I click on "Reinstall" (see attachment), I get a prompt on my Ipads saying "Sign me into iTunes". I have no Users on my Ipads. Via VPP I can install different apps without logging in to that works!

So what can I do to solve this problem? Thanks in advance.
