I should have specified. This is not when conducting a test. This is when you're looking at your cards in a flashcard category you've created. If you click on the card for more detail, it's then where you can't tap individual characters for definitions/information. Thanks.
Ah, for that, long-press the flashcard in the Organize list and then tap “View As Dictionary Entry”; that will bring you to an alternate screen where you can view (and scroll through) flashcards as dictionary entries.
