Hi @djkuo1101,
Thanks for choosing IntellyWP products.
Unfortunately this feature is not still available on our plugin.
You can put this shortcode [irp] to insert a related box searching automagically the best content to fix (based on categories or tags), have you tried to add this shortcode more of one time?
Please be aware that when you will insert the shortcode manually our plugin will not insert any other related box for this article.
Let me know if you have any additional questions sending an email to [email protected] to open a ticket in our tech team helpdesk and will be a pleasure to help you.
Have a nice day
Alex
