I can't seem to find the buttons for self-grading words anymore - instead the grade "don't know" "so-so" "got it" etc. flashes and then fades out. I typically self-grade words with those buttons all the time, particularly when I definitely know the characters but have a hard time with the word that is a compound of those characters.
So is that gone now, or did I just experience a glitch? If it's gone, is there an alternative that doesn't involve marking the characters wrong to indicate that I missed the words?
