I almost always use the system on my iPhone and always on the web rather than the app since the app functionality is so far behind the web system.
The latest release is positive because it is finally responsive, and formats to the phone screen size well, but is now entirely unusable as it's lost the menu. It's now no longer possible to access any other parts of the system other than the dashboard: no flashcards, no points, no forum. There's no way to select any other part of the system other than the first screen presented for you.
Can you please roll this back while you fix the problem?
