I have the same issue with my iphone 3 gs ios 4.3 and ip4s ios 5.1. The nordeous screen shows up for 2 seconds and then the game crashes to phone screen. The multitask still shows the game active, but i just can't get it to open.

But the update works fine with my ipad2 ios 6.1. Which makes me think this is a problem related to ios and facebook app update. Since we all have old version ios, we do not have the most updated facebook (when i try to update, it requires ios 7, and I can only download the latest compatible version). My guess is that if we update ios and get latest facebook app, it will be resolved. The problem is I don't want to change my ios, and I see no point why T11 must make these adjustments, when things were working fine with the previous updates.

Please update if you find any solution for this.
