Hi @meeshymee
Thanks for providing that information and for confirming that you are using the default WordPress block/Gutenberg editor. Since you are using the default editor and not any of the custom theme boxes or page builders that build on top of the standard editor, we would expect that the content analysis would be correct and accurate.
When we say links in absolute format, we mean the full link, including the https://www part of the URL, when you add the internal or external text link.
We checked on the post you’ve mentioned, and in the first paragraph, we do see that there is both an internal text link (anchored to the text “expire”) and an outbound text link (anchored to the text “step one”), so we would expect the Yoast SEO plugin to be able to detect this.
Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict, is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty.
Please test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.
If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts
If you do not feel comfortable to do this yourself or if this does not solve your issue, our Yoast SEO Premium plugin comes with one year of (technical) support.
