I am writing two courses in iTunes U. I am using both the Course Manager website and the iPad iTunes U app to write and publish the course. When I make a change to either of these two new courses (both created in the last month), the updates are NOT reflected on my iPhone. Updates seem to reflect fine on iPad. The only way I can get iPhone to recognize new updates and sync properly is to delete iTunes U app, re-download, and access the courses. But this is only a one-time fix. If I make another change to the courses, they don't seem to sync the changes to my iPhone at all.
Any ideas?
iPhone 6, iOS 8.4, iTunes U app (3.0)
