Custom Fields
Support MB REST API POST meta fields to tags Reply To: POST meta fields to tags



I have investigated this further and I found out that saving meta_box data only does not work for builtin taxonomies: so for post_tags and categories.

If I register a custom taxonomy, everything works as it should.

Any ideas why meta fields for builtin taxonomies do not save? and the update_term_meta never triggers for them, while it triggers fine for a custom taxonomy.
