That's more or less what I thought would happen, which is why I thought I'd wait a couple of days if it wasn't just a general settings issue.
On a vaguely related topic (regards a comment in your last post about spam), one of the reasons I went with social network log in and commenting rather than built-in commenting (Joomla, K2, ZOO) is that, with few exceptions, someone with an established Facebook account is less likely to spam comments - let's be honest, it's a bit of a pain to create a new Facebook page just so you can spam a website comments section!
I tested a few cloud authentication and social network extensions when I upgraded to J3.x, and JFBConnect easily outshines all the others for features, ease of use, etc. And, as I am finding out, the support is absolutely fantastic. If someone doesn't offer the same level of support that I offer my own clients, I'd be reluctant to use their products again
