Each time I do one of the vocab quizes (words for N4) I get 19 questions instead of 20 (I checked the setting and it should be the latter). Any idea what is going on? Thanks!
Sorry for the delay! By chance, if you go to settings > vocabulary > which kanji to show, does it have that third option (recommended from textbooks) turned on?
Yes, it does. Everything went back to normal the following day though. No idea what caused it and why it resolved by itself. Anyway, thanks for getting back to me!
