Main/long description Woocommerce

I know it has been ask a lot of times before but is it nowadays possible to use the main/long description for woocommerce products as meta description?

On your website i also see the folowing

%%wc_shortdesc%% Replaced with the short description of the product. (Available as of Yoast WooCommerce SEO 6.2)

However when i fill in %%wc_shortdesc%% or %%wc_longdesc%% in the products meta description (admin.php?page=wpseo_titles#top#post-types) it will not work. If i look at the sourche of a product it will have no description at all.
