Recently by Facebook photo album embed stopped working on Wordpress. It looks like I need to grant my website new permissions: manage_pages or Page Public Content Access
I found where to requests these under app review. Now it looks like to submit to app review I need to verify my business. Which is requiring me to "Create Business Manager Account."
I select Get Started > Create New Business Manager Account > Input my business name, my name, email.
Then I get "Error notice There was an unexpected technical issue. Please try again."
I have cleared cache and cookies, restarted my browser.
