FAB is anything but, I’m afraid. It has turned the entire user experience into a shambles… almost every important feature of the original Marketplace has been removed… proper searches, wish-lists, reviews… And the new features are confusing… license types…
I am very grateful to the team who develops the Unreal Engine, which is an amazing piece of kit. I can only assume that somebody in Epic’s management innocently decided to out-source the Marketplace to somebody else, and I’m afraid you should be demanding your money back. It’s garbage.
