Hi,
I use the Rating element and the Schema option and I get an error in GSC regarding the Author (of the rating/review) - see attached image.
When inspecting I can see that Pro/Cornerstone outputs author-type as “Thing” and after some google’ing I can see that should “Person” instead.
I guess it’s an error on your end or have I misunderstood something?
