No Content Clusters & Expander doesnt expand

Hi there, 1. I´d like to test the content cluster that comes with the content planer. However, despite me having the best plan available, it tells me that I don´t have any available. 2. Tried the content expander feature and filled it with around 100 words as input. The results were pretty bad. Either very repetetive and twice the same information on one output or simply badly rewriting of my original content. Best Raphael
