Yoast WordPress SEO sitemaps specifically for "categories" on subsites of a multisite not

Hi folks,


I use Yoast WordPress SEO sitemaps for the subsites and primary site of a WordPress MULTISITE NETWORK. All sitemaps that are generated are fine (including pages, posts, and tags) EXCEPT the categories keep showing 404s or Page Not Found. I have tried all the standard stuff out there on this issue (refreshing permalinks, turning XML sitemaps on and off again, adding the Yoast giving .htaccess code on there site (although I could not find one specifically for MULTISITE NETWORK if different) etc.

How can I be sure that all subsites and primary pick up the category sitemaps too in Yoast on a WP MULTISITE NETWORK?
