I tried using a taxonomy field from ACF, but it wasn’t picking up my taxonomy as an option from the Custom Post Type that this post is. Is there a way to get taxonomies from Custom Post Types?
Also, if I’m understanding your suggestion correctly, I’d have to add the tags twice: to the full list field, and to the publicly-displayed field. I was hoping to avoid that redundancy by having the ACF field reference the list of tags already assigned to the post.
