Would like to add that 4+ years later, this is still an issue. Same setup for me:
- Frontend form
- Taxonomy field saving terms to post
- Redirecting in acf/save_post
I mostly understand why this is happening. But to avoid needing to use wp_set_object_terms(), is it possible for me to use another acf filter that fires after the terms are normally saved to the post in order to finish off the redirect?
