Hello,
Thank you for contacting the support and we regret the inconvenience caused.
Firstly, this might already be enabled on your website, but please ensure that the Show Category(s) option is enabled under Rank Math > General Settings > Breadcrumbs:

Then, edit the product page and set the child category as the Primary Category, and see if that gives you the desired output. Here’s how you can set the Primary Category: https://rankmath.com/kb/how-to-choose-a-primary-category/
Let us know how that goes.
Thank you.
Hi, thank you for the quick reply. Yes, the Show Category was enabled and once I make the term Primary it does work. I have an additional question is the ‘Make Term Primary’ created by RankMath or is it always there? I’m using WP All Import to bring in data like this ParentTerm>>ChildTerm>>GrandchildTerm but I need to assign the GrandchildTerm as the Primary. Do you happen to know how I might be able to assign this value from an import?
Thank you so much for your time.
Hello,
The Primary Category is an option of our plugin and you can use the WP All Import’s Rank Math Addon to check if it gives you an option to select the primary term while importing the products.
Hope this helps. Let us know if you need any other assistance.
Thanks.
