I have always been interested in this. I think Jozephor is asking the same question I posted 5 months ago. i.e. I have several custom post types and there is no way for CoverNews to recognize anything but WordPress standard posts, so my custom post types cannot be displayed in the theme.
What I will be attempting is either make a hybrid of CoverNews and some Elementor Pro / Anywhere Elementor Pro blocks for my custom post types, or an entirely new home page with Elementor blocks, appearing a lot like CoverNews.
I don’t know how to use PHP so that is my only option. It would be a tasty upgrade for CoverNews to offer custom post type compatibility. That’s a version I would pay for.
