Hi all. I'm new to all of this. I'm trying to manage an iPad 2 running iOS 9.2, JSS 9.81 and Configurator 2. I'm adding apps through VPP and the JSS and I'm getting the "Please login to your iTunes account to install apps from "xxxx.xxxx.edu" (our server)" on the iPad with a cancel or Sign In option. The iPad is supervised and the apps are free, added - I believe - properly in JSS.
Any thoughts? Has anyone else seen this? Under Mobile Devices > Management - if I update inventory, I see the same message in the JSS under status.
I'm in a similar situation, but when I click on the VPP tab, I get "Content not available to assign to mobile devices".
This message usually appears when you haven't purchased any licenses for that app yet. Even for free apps, you still need to purchase licenses from the VPP portal.
I have receipts for VPP purchases - I can see the VPP purchases - but I don't have the ability to assign them in the VPP tab as above - and I STILL CAN'T INSTALL THEM ON THE IPAD WITHOUT SIGNING IN TO ITUNES. I've tried using the app account we have but the response is that it isn't the correct account. This is infuriating.
Late to the game here, but I had issue where App installed but received the same "log into itunes" pop up, and it kept popping up randomly. My JSS even showed that the right amount of VPP apps were distributed. I contacted JAMF support and here's what they told me to do and strangely enough it seems to have fixed the popup.
This message that you are currently seeing is typically related to the VPP licensing of the application that it is trying to install. If you go into the JSS and go into the device record and click on the management tab are we seeing an app installation messages. More than likely there will be a message.
It looks like these devices are supervised so can we please do the following.
1) Go to the JSS url > Settings > Global Management > VPP accounts
2) Click on the VPP account that you use day to day and click on the contents tab
3) Click the Refresh button next to the application that is being installed currently.
I've just had this issue come up on 3 iPhones in our Org today. I think it's to do with the fact we are currently running JSS v9.101 and these devices are on iOS 12. Hopefully once we upgrade our JSS we shouldn't see these issues again, but in the meantime I've tried the suggestion above about refreshing the VPP licensing.
