Some students can't see all materials in "Posts" section, but all can see them in "Materials" section?
All students have latest version of iTunes U. Some have the latest iOS update, some don't (this doesn't seem to correlate with being able to view the materials). In my course, there are some students who can see all of the materials I have added into each assignment in each post, but there are a large number who can only see one item per assignment in each post. When clicking on the "Materials" tab, however, they can see all of the videos and links?? Any ideas??
