Was there ever any resolution to this? I’m trying to track down an issue I seem to be having a possibly similar issue with ACF Form and using it from the front-end to add images to a post or post gallery.
What’s working:
I can create my form and use it with the uploader to add images to the media library which also get attached to the correct post (records created in wp_postmeta).
What’s not working:
When I look at the custom post type record in the admin the images are not associated with their ACF field. Looking in the database I can see there are no act records for the image or gallery fields in wp_postmeta
