Okay, this had been bugging me for a while.
So you learn a kanji, and then a little while later, you learn a piece of vocab that is just that single kanji alone. They have different readings. If in your reviews you give the vocab answer to the kanji, the screen shakes and it says it wants the other reading (kun? I get them confused).
But when you get the review of the vocab, if you give the kanji reading you get instantly marked wrong. No shaking and second chance.
Why? Can’t it be the same for both? You’re remembering the reading, just the wrong one.
