Google is not using the structured data coming from the app as Snippets
Question: Why is Google not using the structured data coming from the app as Snippets even though it is appearing in Google Rich Results and Google Search Console?
Answer: If there is more than one snippet of data coming from your site (including ours), Google will always choose the data with the fewest warnings. Most of the time, the snippet/structured data coming from our app is the one with the fewest warnings. Please keep in mind though that this does not mean that Google will always turn that data into Snippets in search results pages. To see some reasons why Google does not always display Snippets, and some tips on how to make them more likely to be shown, see this article.
