Just to report that Google Search Console screams about: 

Error

data-vocabulary.org schema deprecated

 

for breadcrumbs..

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

 

We do not use data-vocabulary.org/Breadcrumb schema.

Google somehow sees it and I use stock theme 😐

Do you have a link to the page showing the error?
