Document Uploads must be enabled by your institution for you to create syllabi by uploading documents.
If Document Upload is enabled and being utilized, standard Simple Syllabus features will not be available. This includes importing, the Accessibility Checker, Student Acknowledgment, Reordering, and other built‑in tools.
If multiple Syllabus Access settings are configured to allow users to modify access settings, this will be the only available feature when Document Upload is enabled.
