Freeze - Refresh, Freeze - Refresh, Freeze - Refresh.
Every time I try to do a lesson it freezes after I click "check." The only solution I see then is to refresh the page, erasing all of my progress on said lesson and making me start the entire lesson again. After I refresh the page, it freezes again after two or three questions. This process repeats nearly every time I try to do a lesson. It is very frustrating. How can this be fixed?
