Thanks for your reply. I have removed schema=”true”
from the global site rating schema and have resubmitted for validation through Google Search Console. Hopefully this will fix the product schema.
However, does this mean all my other (landing) pages (non-product pages) will lose their schema in the search results? If so, isn’t there a way we can add global site rating schema to non-product pages and product rating schema to product pages? It would be nice to keep our global site rating schema too, as this makes our landing pages stand out in the search results.
