Hi all,   I've recently setup a class set of 1 to 1 iPads by following the Meraki guide. After testing out the assignments on Schoolwork though I've found that the student iPads cannot open any attachments I send to them. The error message I receive is:   Document cannot be opened - Make sure "Document" is available in your "Maths Group" Schoolwork folder in the Files app, or try again later.   Handout: number userID: Student Apple ID Handout state: Published, Successfully Authenticated, errorCode: failedToOpen, noSuitableUrlForAsset, 2   Does anyone know which setting might be blocking this? I've made sure to enable all iCloud settings I can see.   Thanks ... View more
