Oups! “woocommerce_save_product_variation” action does not work properly.

Replace with:

add_action( 'woocommerce_save_product_variation', function( $variation_id, $loop_index ) {
	if ( !isset( $_POST['acf_variation'][$variation_id] ) ) {
		return;
	}

	if ( ! empty( $_POST['acf_variation'][$variation_id] ) && is_array( $fields = $_POST['acf_variation'][$variation_id] )  ) {
		foreach ( $fields as $key => $val ) {
			update_field( $key, $val, $variation_id );
		}
	}

}, 10, 2 );
