New post won't update
When I create a post with assignments, I cannot access the updated course information on iTunesU on my iPhone 6 or iPad mini. One of my students cannot either (iPhone 6 plus and iPad mini), but the rest haven't had any problems. I can see all the updated information on the Course Manager from my Macbook Air running Yosemite, but not from my iPhone or iPad. Sometimes iTunes will push an update for my iPhone, but the app itself will not update. Is this a known bug, or is there something I can do to force iTunesU to update on my iOS devices?
I've tried posting assignments with no assignments, no due dates, hand-in/grading disabled/enabled, nothing seems to make a difference.
