I am using the enterprise version. I just migrated from V5, after some obscure interaction problems between AcyMailing and content builder, preventing me from sending mails. I still use the HTML editor, which I prefer to AcyMailing editor.
I have understood that add-ons replace "balises" of V5. But I can not activate the add-on to insert a Joomla article. I have not found anything on the subject in the available documentation, although this is a very basic and convenient feature. The V5 syntax to incorporate Joomla modules has been migrated in my customized templates but is ineffective.
I would appreciate some guidance and documentation.
