The issue here is that the user wanted to know if we had any formal guide on how to Move from Layouts to Blocks. Solution:
Unfortunately we do not have a formal guide on Moving from Layouts to Blocks. However we do have documentation on how to use our Blocks plugin at the link below.
The issue here is that some of the user's posts were displaying differently from others.
Solution:
Upon checking the user's website it turns out that some of their posts didn't have their content template assigned to it.
If this is happening to you then I would recommend going to the Content template that you've made and under the Usage table click on "Apply to All". This will assign the content template to all the posts under the assigned post type.
