Tapping too quickly after answer will skip a card

Background: when you’ve answered a card, if the answer is correct then instead of having to tap “next” you can just tap the background and you will advance to the next card.

If you do this too quickly, you will sometimes see a card appear briefly but then immediately advance to the next card. That card will not show up later in the review, so it is effectively skipped.

This was observed on the iOS app.
