Who says that they don’t need it to do their job?

Here’s a very basic use case: a Markdown field. After saving the field, the converted value is saved to the database in a separate field (using acf_update_metadata($post_id, $name, $value, $hidden)). That’s done so we’re not saving the original value as an array, allowing easy querying via WP_Query or the like.

When rendering the input field next time, we show a preview of the converted markdown field, but we need the $post_id to get the correct field from the database (acf_get_metadata($post_id, $name, $hidden)).

I will open a support ticket, thank you.
