Search Console not finding urls from sitemap

Dear support,

Google search console is picking up the sitemap generated by yoast. However no URLs are to be found for indexing.

We also tried if some pages are indexed by Google by using site: https://www.headfonia.com/review-fiio-fh9/ for the latest articles published on the site.
It seems only the images on the page are indexed.
We double checked the sitemap and the XML seems to check out ok. URL’s are there but only the images on the page get indexed after publishing.

We have asked for re-indexing several times but the sitemap does not show the URLs.
Not sure what we can do differently at this point.

Any ideas?

Have a lovely Christmas.
