I'm trying to setup rich pins and am stuck in the validation step. It has an error on Aggregated Rating and Authors. But I can't for the life of me figure out how to resolve these issues! How do I problem solve these in order to get validated?
I'm having a similar problem! When I enter my URL and click validate, I get "504 Gateway Timeout" error. I have enabled Open Graph meta data in Yoast plugin and still doesn't work.
Both the aggregate rating and author options are marked up as 'optional' so they shouldn't matter anyway. I've reached out to Pinterest a couple of times now but still no solution - I'll post on here if something comes up!
