But when its been used for a little while, it starts getting glitchy (freezing, saying answere are wrong for assessments when theyre not - so you have to shut the app down and load again. Also, it lacks a way to Report a problem or contact them. Tonight, I got to Page 4 of Chapter 1 and its just a blank grey screen saying “Assessment is Loading” Tried refreshing the App, but it didnt help.
