Hello Babouz,
Thanks for reaching out about your custom post type taxonomies. Testing in Yoast SEO 17.2 and WordPress 5.8.1, we couldn’t reproduce this issue. We created a CPT and a taxonomy under it, then defined a global meta description for the CPT. We went ahead to specify a meta description for one of the taxonomies. The end result is that the global meta description does not show up, instead, it shows the specific meta description for just that taxonomy.
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.
Hello ! thank you for your reply.
Sorry I miss to tell you that it was a taxonomy hierarchical, and if I set a new title/desc to the parent taxo, all is good, but it doesn’t work for the child…
All my apologies, I found where was the bug… it was a function in my theme that was globally overriding the taxonomy title of second level…
