We have feedback that the "About" expand button on the class page in the mobile view is not obvious that you click it to expand and see what the course is about.  We can't edit the button to underline it, or add an downward arrow to indicate that you click the button to expand to see the "About" content. People are tapping the picture, the title, and the course button (which is a button that does nothing). 

Can you make the "About" button editable, or at least add an indication that clicking it expands to reveal the content in the mobile view?  Picture attached.
