I'm seeing several problems over and over. I had some of them and they were solved last night within hours of the change. For some odd reason, the fixes haven't propagated across WordPress. So, be sure to contact Support at the above URL. I don't think they're making an effort to be in these Forums, but I *do* know that Support is available all this weekend due to the change. If they keep hearing from people and getting the same problems over and over, it will finally penetrate someone's head to start fixing things.
