I added a new post to my iTunes U course and it is not showing up on one of my student's iPads. She has only one Apple ID on the iPad. Any assistance is appreciated.

A new post to my iTunes U course shows up in my course both on my Mac and my iPad Air, as well as on other students' iPads, but for one single student. We have closed the app and forced shutdown. Student recently added more icloud space, but that is all. iPad is up-to-date in terms of iOS and iTunesU app. The student has only one Apple ID associated with her iPad.

We have reposted two more times. The second time the post showed up for a few seconds, but then disappeared. It does not show up under any other section (assignments, discussions, etc). Any assistance is greatly appreciated.
