Firstly if something does not work for you, the etiquette is to post on the support forums rather than lashing out. I don’t do this for the money (there are no upsells), and it disheartening and unfair to trash a good plugin. Can you please delete this post and do that?
Anyway it does work, see example here:

that it does not work on your setup is most likely a problem with your other plugins, many of which are terrible. That is why the faq mentions deactivating all other plugins if you have issues
