We have an LTI app in Schoology that supports syncing grades from our tool to the Schoology platform. Everything about the integration is working as expected, except the assignments in Schoology end up with a null and uneditable due date. We are sending the startDateTime and endDateTime in line with the LTI Grades and Assignment spec and it's working as expected in other platforms.
Is a null due date the expected implementation behavior for a synced assignment in Schoology?
