Course Presentations
Dear Community,
I have created very large interactive books with numerous course presentations. I used the Lumi desktop software to create them. Yesterday I opened another student's course presentation with Lumi.
Problem: now all (!) my own Course Presentations (inside all my interactive books) are no longer displayed. (Screenshot attached) I see nothing but white boxes. It seems to me that I have received a different/newer version of the course presentation?!
