I came here with the exact same question. I have captions for all of the videos in my app, (none), so I think I should select "captions" in my nutrition label. Leaving it unchecked suggests that there's content that is inaccessible, which is untrue to the point of being intentionally misleading. And that mislead seems worse to me than claiming I have captions when I have no video at all.

[quote='843657022, DTS Engineer, /thread/788023?answerId=843657022#843657022'] It seems incorrect to indicate the presence of captions when they aren't there in an audio or video asset. [/quote] Perhaps, although I DO have captions for every single video in my app, (which is zero). The reverse mislead, that some of my content is inaccessible, seems like a worse error to me. I have no such inaccessible content. Clearly, what's needed here is something more than a 2-state response. We need to be able to say "Not applicable - no videos to caption".
