The newest version (1.7) has a bug that won’t load it past the white screen—the screen that is present after the logo screen fades. Can’t use app anymore nor download an older version. Now I have no app to use 2 days before spring quarter starts. Nice update. Thanks.

There seems to be an error where I can’t leave the session after completing the lesson and I have to exit out of the app in order to take the quiz.
