Search Console Now Checks the Validity of FAQ and Q&A Structured Data That Is Below the Root Entity Level
https://support.google.comSearch Console now checks the validity of FAQ and Q&A structured data that is below the root entity level. Previously, they only checked entities at the root level. Therefore, you may see an increase in valid/warning/invalid FAQ and Q&A items to reflect an accurate count of root and nested entities that we found on your site.
This might be the reason for the FAQ Schema issue with Yoast a few days ago.
