Full of bugs that renders it outright useless – Bookshelf Review

The app was good at the start, collaborated with the uni I was studying. But now, its completely inaccessible, you have to sign in every time, and even the sign in page is so buggy that you cannot see the texts you’re typing (email address). I have re-downloaded the app hoping that it will fix the issue but to no avail! How do I access my books?!
