Hi Walkman,
Sorry to resurrect this post, I thought I had replied before but I obviously never did! I work in a fairly large secondary school with over 500 individual classes, and the iPads are booked out to whoever needs them. We are set up on Apple School Manager, but it takes so long for the students to find their class, that it's actually quicker for them to type in their email address.
If there isn't a way of pre populating the domain, is there any other solution you can suggest?
Thanks alot for your help.
