Has anyone had anyluck adding the meta property for Facebook AppID? I am trying to update the cache that Facebook has for my site because the text is wrong when you copy and paste my URL into facebook share.
You can update the cache with the debugger tool, http://developers.facebook.com/tools/debug but your app has to be approved.
So I created a simple app and tried adding the meta property in my head section of Advanced customizer, but its ignored and the SmugMug app id is used instead
<meta property="fb:app_id" content="myappid">
