I am having a similar issue, but just a little different. I have a search filter that can look into the acf fields for the taxonomies, so I made taxonomy fields in ACF and matched the name with my term names for WordPress. But when I input tags and categories into the boxes provided by WordPress, they do not show in the fields I created with ACF. But, if I first put them in the ACF field, they then show in the WordPress one. I am using the ACF taxonomy field. Is there a way to make that bidirectional so they both show in both spots? I have the post 2 post plugin for bidirectional, but it doesn’t seem to work with taxonomies.
