Breadcrumbs to follow yoast primary category

The Yoast plugin allows for primary categories to be chosen for posts, I would like the enfold breadcrumbs to follow the link structure using that, giving priority to the primary category rather than just choosing the category alphabetically. I tried to drop the piece of code from this: https://kriesi.at/support/topic/make-breadcrumb-path-follow-primary-category/ into my functions.php of my child theme but it didn’t work.

For instance, I have chosen ‘trips’ as the primary category for this post which shows up in the yoast link – http://www.themajesticwild.com/trips/obabika-loop/ but it’s getting pulled and shown as http://www.themajesticwild.com/photos/obabika-loop/ by enfold. How can I change it to be consistent?
