Problems with material links in iTunes U for web
If you have trouble adding links to iTunes U for web, keep the following in mind:
iTunes U cannot add an iTunes Store link if the link you specified:
Is not accessible at the time
References an unsupported material type
References an item not currently available in your country
When this occurs, iTunes U displays the equivalent web URL link in the preview pop-up pane. You can click Add in the preview pop-up pane to add the material as a web link instead of an iTunes Store link.
