Hi,
1. Product snippets
The remaining errors are caused by the carousel templates (used for related products, cross-sell modules, etc.) which still had `schema.org/Product` markup on each item. We had fixed the category listing templates but missed the carousels. This has now been fixed as well. Please download the updated 6.4.0 package from your member area and reinstall.
After that, you can verify the fix immediately by testing your pages with Google's Rich Results Test at
search.google.com/test/rich-results
(use the "Test URL" option). The Search Console errors will clear once Google recrawls the affected pages, which can take a few days to a few weeks.
2. Breadcrumb category URLs
The breadcrumb on the product page was building category links using the product menu item (e.g. `/comprar/`). Since the Joomla SEF router needs a matching view to generate the correct URL, using a product menu item for a category listing URL resulted in URLs without the proper prefix (e.g. `/cajas-para-tartas` instead of `/catalogo/cajas-para-tartas`).
The fix now looks up the most appropriate category listing menu item for the breadcrumb links. It checks all your category listing menu items and selects the one whose configured root category is the closest ancestor of the product's category. This way, if you have `/catalogo/` pointing to your main product categories and another menu for a different section, the breadcrumb will use the correct one.
This fix is also included in the updated package.
