Suggestion for minor change to prevent frustration
When a mistake is made on an exercise where you have to type the response in the language you're learning, the pop-up window covers what you typed so you can't compare the correction to what you typed and see what you got wrong. This is infinitely frustrating because if it's an accent or something, I need to see which letter I erroneously put it on so I can avoid doing it again.
On what platform do you get this problem? I only get a pop-up window on the Android app, where it can be dragged out of the way.
