I have come across this twice now.
More than one teacher has created an assignment. They can open it and see that it is correct.
A few students have had problems. When they open the assignment, it is blank pages (the exact number of pages the assignment would have shown). They can write on the blank pages and submit their work. The teachers open it and it is blank for them with the students annotations on it fully intact.
Anyone else run into this problem?
