How to use shortcode for new post title?

Ugly workaround:

// After save post
add_action('acf/save_post', 'my_acf_save_post', 30);
function my_acf_save_post( $post_id ) {
   // Following keys are FG name and user defined id name
   // Both are "hard" constants
    $title = $_POST['acf']['field_5f3a38f2a4c08']['field_5f3a3939a4c09'];
    error_log('acf after save_post  title='. $title);

    $my_post = array(
          'ID'           => $post_id,
          'post_title'   => $title
      );
 
// Update the post title into the database
    wp_update_post( $my_post, true );
    
    if (is_wp_error($post_id)) {
        $errors = $post_id->get_error_messages();
        foreach ($errors as $error) {
            echo $error;
        }
    }
  
}

I’ll be using this until more info on default post title is provided! Thanks for this!

Actually, I made this a little less ugly (and with no error logging):

// After save post
add_action('acf/save_post', function ( $post_id ) {
	$values = get_fields( $post_id );
	extract( $values );
	$my_post = array(
		'ID'           => $post_id,
		'post_title'   => "{$first_name} {$last_name}, {$city}, {$state}" 
	);

	// Update the post title into the database
	wp_update_post( $my_post, true );  
}, 10, 1 );
