Problem:

When I create an archive page or a single page, I want to automatically load the relevant product for each post.

Solution:

I suggest you try many-to-many relationship, for example:

Relevant Documentation:

https://toolset.com/course-lesson/displaying-related-posts/#displaying-many-related-items

Problem:

Occasionally I need to use multiple templates for a post type but unless I specify that the template is the default for the single display, all the fields of that post type are not available to me.

Solution:

Please edit the content template, in option "View with:", find and select a specific post, and test again, see my screenshot view-with.jpg

Adding the Cred shortcode to show the form does not work in Page Builder

Solution:

To make sure that there is no conflict with the page builder, change the shortcode from something like:

[cred_form form="123"]

To this:

{!{cred_form form="123"}!}

Replace [ with {!{ and ] with }!}
