Problems with files and collaboration in Schoolwork
If you have trouble with files and collaboration in the Schoolwork app , try these suggestions.
Confirm all teachers and students are using the same version of Pages, Numbers, and Keynote. If teachers or students are using different versions, make sure they all upgrade to the same version.
To be sure you can open all Handout files on your iPad, verify “Allow iCloud documents & data” is not restricted (Go to Settings > General > Device Management > Profile > Restrictions, then confirm there is no “Documents in the Cloud not allowed” entry). If it is restricted, contact your school’s IT administrator.
When editing a shared file, confirm all your changes are saved. Schoolwork might overwrite changes if another teacher or student edits a file you shared with all students (“Students collaborate together on the same file”) at the same time you edit the file.
