making Rise compliant for visually and audibly impaired

Hi Chino. We are so happy with Rise and all of the updates to accessibility and conformance. I am creating some tip sheets for my team on ensuring 508 compliance when using Rise. I am using the 508 Rise Conformance Report. I see that several blocks are not fully keyboard/screen reader accessible yet (I have noted that for my team in our cheat sheet), but I noticed flashcards aren't listed. When I have tried flashcards with NVDA I have issues getting it to read the cards when flipped. Am I doing something wrong with the screen reader, or are flashcards also not accessible yet via the screen reader? I want to make sure I am giving my team the most accurate info. Flashcards are one of our most popular blocks. 

Thanks!
