I'm having trouble with a post - I'm trying to post it on facebook via a wall post, and the thumbnail is not showing up.
It's only doing for this certain post - that I posted up about 4 hours ago. I've tested it with previous posts and the thumbnails are working fine.
I've run it again the facebook linter, and it's picking up the correct OG:image. So I can't figure it out. Is it because it's only a recent post? I've tried it with previous posts and it seems to be working ok.
