Review snippet Enhancement report
To help site owners make the most of their reviews, a new review snippet report is now available in Search Console for sites that have implemented reviews or ratings structured data. The report allows you to see errors, warnings, and valid pages for markup implemented on your site.
In addition, if you fix an issue, you can use the report to validate it, which will trigger a process where Google recrawls your affected pages. The report is covering all the content types currently supported as review snippets. Learn more about the Rich result status reports.
