NEW IN RISE 360: Closed Captioning

It's great that Closed Captions has been added to Rise and from an accessibility perspective that's even better!  I've just added CC to a course I'm building and followed the instructions but I can't test it in Preview mode - the instructions say you have to test it in an LMS or on a web server. 

I'm working with a large organisation at the moment and they have tested the Rise courses we are building from an accessibility point of view. They did come up with a number of issues and I'm aware you are working towards certain enhancements. 

If CC can't be tested in Preview mode, and only exported into an LM or web server, then how should accessibility testing be done? Via a link or should it also be exported to an LMS or web server to get a true testing?

Looking forward to hearing from you :)
