I have typed kanji answers enabled, and my mastery schedule is asking me to enter kanji which I have never studied before.
I suspect this is due to how I convert answers into kanji on mobile, which is that I type in kana and it presents me with kanji and match or are close to words that are spelled using those kana. Sometimes this means I enter answers I know are correct, but which may use kanji I haven't studied. If it's an intended effect then I guess that's my own fault, but is there anything I can do to stop it from asking me to enter kanji I haven't studied on renshuu yet?
