Now Google supports BreadcrumbList
Since some days ago Google didn’t support (its) schema.org breadcrumb implementation: https://schema.org/BreadcrumbList
That statement wasn’t fully right: I had many clients with BreadcrumbList and regular breadcrumb rendering in SERP. But… finally it’s truly supported: from some days Google changed its documentation, and add support to the BreadcrumbList semantic object:
So, now we can add the breadcrumbs using microdata and JSON-LD too: eureka!
