What happened to step by step? – Wolfram Calculus Course Assistant Review

This used to be a 5 star app, but recently I have found that it no longer gives the step by step instructions that it used to give. The button is still there, but when you press it nothing happens. It just shows the same thing (no steps) but offers to hide the steps that aren't there.
