Google can’t detect Rank Math’s schemas!

Hello @anguschang007,

Thank you for contacting the support.

Upon checking your website, we can confirm the breadcrumbs schema was added by our plugin. You may check the Rich Result Test instead: https://search.google.com/test/rich-results/result?id=yzvmdFIsLq82Zo22hoeAOw

The reason why you don’t see it in the schema.org validator is because the breadcrumbs schema entity was nested to the BlogPosting schema which is perfectly fine. Please see this screenshot for your reference: https://i.rankmath.com/i/tcAZO4

Hope that helps.
