I have ML DP4 with Facebook integration installed. When logging in to facebook.com, ML asked me if I want to integrate FB with OS X, which I did. Facebook is now setup in System Preferences and in Notification Center, I can post to FB, but I'm not getting ANY notifications. Same with Twitter. I set it up manually in System Preferences, but then it always tells me that the password is incorrect. When I log in to twitter.com, I can see OS X integration in Settings-Apps though. But no Twitter notifications coming in either. Is receiving FB/Twitter notifications working for anyone?
