I get notices like “this post can’t made made to wall at the moment, try again in a few minutes”. etc…. and my friends are experiencing the same thing. Tracy used a hashtag at Twitter to find the linked source of information.
As confirmed HERE noone can use FB properly at the moment.
We can still use the feature to pm each other, but that is about the only thing working properly at the moment. The games are playable, but bragging that you cleared out a level can’t be done.
So I guess we all just have to wait to update our Facebook status right now.
