RankMath compatibility

Hi, In june you annouced the RankMath Compatibility with Primary Cat
“Added: Rank Math Primary Category support added”

After some test, seem that it does not work as expected.

Context:
I use RANKMATH
All my product arre setted with a RankMath Primary CAtegory (work the same with Yoast)
I made mapping of each woocommerce categories to one Google Category

Feed should contains Google Category corresponding to my RankMath Primary Category.

How do i achieve that ? I’ve made some test, and seem that your plugin never map Google_cateroy with the primary cat …

I am doing something wrong ?
