the core function of the plugin John is to give you the ability to easily add opt in forms before and after your post articles. That’s it. and the core functionality of the plugin provides that.
we have had many users who have been happy with using just the free version and some of them have been doing some amazing things despite the *limitations* you spoke of. in fact, we even featured one of them here https://www.magicactionbox.com/featured-showcase-create-as-folk/
as for your issue, you need to go to the blog post you want to show the action box in, edit it, and assign an action box to it (like it says in the guide). You’ll also need to specify whether you want to show the action box before or after the blog post.
if the action box still doesn’t show up, could you list the steps you did so we can check if there’s anything we need to check.
If you want us to help you, then you’ll need to at least participate in troubleshooting the problem. simply saying “it doesn’t work” doesn’t really help.
