I know this is possible, because I think I’ve seen something similar happen at other times. I don’t remember specifically, but I think WankiKani did EXACTLY as I was describing when I was prompted with “子” and I entered “こ” when it was looking for “す” or “し”, which I think is a case of me entering the “Vocab reading” in a “Kanji” question. I think.
EDIT: I just tried to answer the “Kanji reading” question for “下” (pink background)" with “した”, and it said “Wanikani is looking for the On’yomi reading”. WHY can’t the reverse be true as well?
I know this sort of thing SOMETIMES happens, so why can’t it ALWAYS happen? I think marking “か” as wrong as “フキュ” or something else 100% wrong in this case will only serve to weaken my association between “火” and “か”.
At least do this for the single-kanji-only vocab questions.
I’ve also seen one or two cases where I wasn’t thinking properly and entered the meaning when it was asking for a reading only for it to prompt me to enter the reading instead. All of the other times I did that, it just marked it wrong. Why can’t they all be like that?
This is getting really frustrating right now, and I’m on level 3. If this issue gets TOO frustrating, I assure you that I won’t be buying a subscription plan to get access to level 4 and up. Little things like this are excusable in a free service, but as soon as I start paying money I expect quality. Heck, maybe I could find another Kanji learning system that specifically teaches which readings are On and which readings are Kun. Maybe if I remembered that I would stop trying to read “女の人” as “おんなのじん”.
