I’m just using it with the default WP classic editor. I’m doing ACF Pro with CPT UI. But I think I found a workaround for now that looks to be doing the trick by using WP User Frontend and creating a form to match my custom fields.
I know it’s been a while since anyone has posted on this and most of what I can find nowadays is pretty ancient. Has this ever been updated with any of the ACF pro releases or do I still have to put “_thumbnail_id” in the image field?
