Hi, is there any update or news about repeater field ?

i was able to save normal fields to product variation but when i create repeater field it doesnt save the value, here is my code;

add_filter('acf/location/rule_values/post_type', 'acf_location_rule_values_Post');
function acf_location_rule_values_Post( $choices ) {
	$choices['product_variation'] = 'Product Variation';
    return $choices;
}

add_action( 'woocommerce_product_after_variable_attributes', function( $loop, $variation_data, $variation ) {
    global $abcdefgh_i; 
    $abcdefgh_i = $loop;
    add_filter( 'acf/prepare_field', 'acf_prepare_field_update_field_name' );
    
    $acf_field_groups = acf_get_field_groups();
    foreach( $acf_field_groups as $acf_field_group ) {
        foreach( $acf_field_group['location'] as $group_locations ) {
            foreach( $group_locations as $rule ) {
                if( $rule['param'] == 'post_type' && $rule['operator'] == '==' && $rule['value'] == 'product_variation' ) {
                    acf_render_fields( $variation->ID, acf_get_fields( $acf_field_group ) );
                    break 2;
                }
            }
        }
    }
    
    remove_filter( 'acf/prepare_field', 'acf_prepare_field_update_field_name' );
}, 10, 3 );

function  acf_prepare_field_update_field_name( $field ) {
    global $abcdefgh_i;
    $field['name'] = preg_replace( '/^acf\[/', "acf[$abcdefgh_i][", $field['name'] );
    return $field;
}
    
add_action( 'woocommerce_save_product_variation', function( $variation_id, $i = -1 ) {
    if ( ! empty( $_POST['acf'] ) && is_array( $_POST['acf'] ) && array_key_exists( $i, $_POST['acf'] ) && is_array( ( $fields = $_POST['acf'][ $i ] ) ) ) {
        foreach ( $fields as $key => $val ) {
            update_field( $key, $val, $variation_id );
        }
    }
}, 10, 2 );

function xxx_admin_head_post() {
	global $post_type;
	if ($post_type === 'product') {
		wp_register_script( 'xxx-acf-variation', get_template_directory_uri() . '/inc/ss.js', array(
			'jquery-core',
			'jquery-ui-core'
		), '1.1.0',
			true ); // Custom scripts
		
		wp_enqueue_script( 'xxx-acf-variation' ); // Enqueue it!

	}
}

/* actions fired when adding/editing posts or pages */
/* admin_head-(hookname) */
add_action( 'admin_head-post.php', 'xxx_admin_head_post' );
add_action( 'admin_head-post-new.php',  'xxx_admin_head_post' );
