Some of my patrons that are using the Mobile App have had issues with the mobile apps identifiers using VoiceOver on iOS. For example when VoiceOver is turned on and the user goes through the different resources on a course page they are not told when they are on forum/assignment. Unless the forum/assignment has forum or assignment in the name the VoiceOver user won't know what the item is.
Another issue, that might fall under a bug report, is that the link button that takes you out of the app to a web browser page does not work when using VoiceOver on iOS. VO goes over the button and states what it is, however when the button is double clicked it does not open the web page.
