I have an Asset publisher configured to only show web content for a certain structure
Asset Type -> Web Content
Asset Content Subtype -> News (my structure name)
I also added that the web content must contain "any of the following categories" and I picked one of my categories:
Vocabulary -> News
Category -> Alex
When I create a webcontent article using the specified structure and when I set the category on the article, the AP portlet doesn't show the entry.
