Errors in Google Search Console

Hello Luis, thanks for using YASR!

If you want to insert that fields, when you edit your post or page, at the bottom of the editor screen, you’ve a metabox as you can see in this screen https://ibb.co/dbFhJvY
You can fill that info there.

Please note that are not errors but just warnings, so are not mandatory and you can safely ignore them.

Also, I suggest this reading https://yetanotherstarsrating.com/docs/rich-snippet/reviewrating-and-aggregaterating/

Best,
Dario
