Bing index issue

Hi

I’m using Yoast SEO plugin and have no problem with google, but Bing only indexes my categories and not posts.

I’ve verified my website on Bing, even sent sitemaps to Bing manually and checked Bing page previews to test if Bing can access my posts. The results were fine, but in the Bing index explorer there are just categories and no posts.

Any help would be appreciated.
