It also does not work with the News Show Pro GK4, which I was expecting, as it was promoted with, working with "Your articles & modules will now be able to appear in multiple categories."
Also already waiting for a support reply for 12 days!
We sent you an email regarding the component not working with all 3rd party plugins. There is no way we can support that and did not mean to imply that it does. It works great with all standard Joomla articles/modules. We never said it worked with 3rd party plugins.
If you send me an email to email@example.com I will get your information and send you a refund via paypal.
