Good afternoon Nicole.
We have tried 3 different ways of embedding our PDFs. The first one uploading as an attachment, then opening the resulting link (from your hosting service) and copying the URL into the embed code bar. The second one a Google Drive URL, and the third one a Calameo URL. Management didn't want them to show just like an attachment so this would be our last choice. As our courses are private, I'll send you a small sample with copied parts issuing this problem.

Thank you very much!
