Read words are no longer highlighted


I remember that there used to be sort of a rectangle that moved from word to another word as they were being read. It miraculously disappeared. Is there a way how to activate it somehow please? Maybe somewhere in settings? Or has it been removed in some of the patches?

Thank you.

@Jeffgrav - The rectangle is still there. Just click or select your first word in a lesson and you will see it. It moves along as you move from word to word.
