We have dozens of students using managed and supervised iPads under Casper/ JAMF and want students to be able to export from Garageband to .m4a and provide the files to their teacher.
It would seem that the best solution is to use the iCloud documents feature from the share-sheet. The teacher (a PC user) could then just access iCloud.com from a browser, dropbox-like, and download the files there.
We've used configuration profiles to restrict various iOS features, and I can see what to un-tick to enable iCloud generally, but how do I add the credentials of our generic school AppleID to iCloud on multiple devices so that Garageband can export to that iCloud account easily? Surely I don't have to log in to iCloud individually on each iPad?
