Problems with files and collaboration in Schoolwork
If you have trouble with files and collaboration in the Schoolwork app , try these suggestions.
Confirm that 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 make sure you can open all Handout files on your iPad, verify that “Allow iCloud documents & data” is not restricted (go to Settings
> General > Device Management, then tap a Mobile Device Management profile. In Profile, tap 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 that 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.
If your school’s IT administrator did not install the Files app, you and your students can see files in Schoolwork but cannot open the files. To make sure you and your students can open all Handout files, verify that the Files app is installed on all devices, or contact your school’s IT administrator.
