Breadcrumbs in the Customizer: If your theme declares support for yoast-seo-breadcrumbs, you will get a Customizer panel for Yoast SEO breadcrumbs. Automagically.
This doesn’t appear in customizer. Can this be added in future update.
Cheers
Hey Dennis,
Thanks for pointing that out! Unfortunately, the guys don’t keep track of requests here in the support forums. You’ll have to head over to the User Voice Forums and add it there.
