"Discuss Sentence" button doesn't work
Is it just me, or does anyone else have an issue where the "Discuss Sentence" button is visible but cocking it doesn't work? Some lessons it works, and some it doesn't. If I really want to discuss the sentence, I have to re-start the lesson, find the sentence again and then hope the button works.
This happens to me even if no one has commented yet. I can click the button, but no pop-up appears.
Then it could be a glitch. On such occasions, you can lookup the sentence after the lesson.
