Articulate Player app accessbility

My colleague is using Articulate Storyline 2 to create web-based training modules about web accessibility (of all things). He was careful to make the content of the training accessible. However, when we try to view the content on a mobile device (e.g., iPhone or iPad), the Articulate Player app does not allow access to any of the content with VoiceOver. When VoiceOver is turned on, none of the content or navigational buttons are identified or even able to be activated by touch, strangely enough (With VoiceOver turned off, one can activate the navigational buttons as normal).

Any suggestions for being able to play these training modules on an iOS or other mobile device? FYI - we haven’t yet tested the training modules on an Android device.

Thanks in advance,

John
