No "category" generated on indexing from meta property "article:section" as per docs

It should work yes, can you give us personification access to double check?

Forgot to update here, for some reason the Netlify crawler was running on a cached instance of our Website, so it didn’t have the latest <meta> tag added. Just had to do a re-deploy, and it worked great!
