Where's the EXP graph?
When I first started Duolingo it was visible on the right, just below my EXP goal. However, upon completing a classroom assignment (I had tested it out to see how it functioned) that space is taken up by the assignments list, even after deleting the classroom and attempting to unenroll (which for some reason didn't work). How can I restore the graph?
UPDATE: Turns out deleting all my cookies for Duolingo fixed the issue.
When I joined a classroom, the XP graph (Daily Goal) disappeared. On leaving the classroom, it was restored.
I assume their logic is, that you do not need one, as the teacher will be tracking your activity. You just do what the teacher assigns.
Perhaps, if you deleted the classroom, before leaving it, then you may have confused it. I would report as a bug.
