Member not added to Group Members

Hi, I'm testing a new membership plan payment, but it is not neither adding the user to a group member nor to a joomla user group.
I set both the category and user group as Empresas. The payment test was completed, and the subscription status is set to Active.

Never mind. It was premature!

Thanks Hugo. For your information, we have now have better documentation site at membershipprodoc.joomservices.com/ , so you should use new document site from now on
