This primary category setting is used when you assign a post multiple categories and want to set a primary.
Uses the WPSEO_Primary_Term class in Yoast SEO.

One more question please Brad…if I view the post on a moblie device, the thumbnail featured images don’t display, only the link anchor text appears for each related post. How do I get the thumbnail to remain, even on mobile devices?
Remove this CSS rule from your style.css file.
Great, that worked perfectly. Thanks man!
Hi Brad, I installed this and it works, thank you.
How do I get it to only display the three latest posts within the Primary category? At the moment it displays 3 random posts that change each time you refresh the page.
Thanks, Jonathon
Sorted, I changed the ‘rand’ within the functions file to ‘date’. Thanks, works great!
I have a few different categories on my blog.
For each blog post, I only use one category.
Will this enable displaying related posts only from the same category?
At the moment my blog shows the 3 most recent posts regardless of category.
It will and you can also use this code https://wpsites.net/web-design/how-to-code-a-custom-block-for-a-related-posts-query-in-genesis/
