The FAQ rich-result markup no longer appears on your property pages. This is intentional.
Why this happens. Conversion Kit 1.133.0 removes the FAQPage JSON-LD that the Review Insights tool used to emit. Google retired FAQ rich results for almost all sites, so the markup no longer earns an enhanced listing, and keeping it risked structured-data warnings instead.
What your guests see. The FAQ content guests see on the page still renders exactly as before. Only the machine-readable FAQPage markup is retired.
What you need to do. No action is needed. Removing markup Google no longer uses does not affect your rankings.
