Doesn't Seem to Work – Enki: Learn Coding/Programming Review

Received my invitation code and used it to sign in. So far, so good. It asks me to select a few topics for coding workouts. For a given topic that I select, it asks me whether I want basic, advanced, etc. But then once I have selected a level, nothing happens. I just get a back button which takes me back to the list of topics, where nothing appears to be selected. There are no other nav choices and no help (no how-to docs on the website either), so as far as I can tell, this app is broken. Disappointing.
