Flashcards function

After you turn over the flashcards and look at the answer, and you’re going to click ‘nailed it’. When you click it, the answer of the next question will briefly appear for a milisecond and flip back to the question. It’s quite confusing because I don’t really know if I’m answering the question correctly because my brain have seen the answer right before the question pop up, or I’m remembering the content correctly.

Plz fix this bug! Thx a lot~
