Too many free iCloud accounts
I am the tech coordinator at a school with ~600 iPads (mostly iPad 2s, some iPad 3s, and around 180 iPad Airs)
As students graduate and/or leave the school, we reuse their iPads and give them to new students.
When doing so, we have some iPads that have been used by over 3 users over its lifetime, and, in turn, we have run into a decent number of iPads that are giving the error that says "The maximum number of free accounts have been activated"
I understand why this is in place: so people don't create a ton of accounts and have unlimited iCloud storage. But this is extremely annoying in the education (and business) systems where devices are reused.
Is there anything I can do? Or maybe is there anyone I can contact to reset the counts? I have all of the order numbers and that good stuff, so I can provide the necessary details.
iPad 2, iOS 9.0.2, Also on iPad 3 and iPad Air
