Reply To: Swap code for production

Try to add the following PHP code snippet to the child theme functions.php file to do this

add_action(
	'wp',
	function() {
		remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_excerpt', 20 );
		add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_excerpt', 31 );
	}
);
