Great Courses improvement

iOS & iPadOS

Hi all! I just gave the app called Great Courses a try on my iPhone 6 Plus. I couldn't set up past creating a user account. The mobile site is not accessible past being able to reading it and clicking some of the links. The buttons are not accessible. The app is not a help either until you are already set up barring creating a new user account. Have you also incountered this problem?
