I have a similar problem in which everything to do with the main game will load aside from my Friends List and Clan (though I Myself am not in one, I've been letting a few requests sit there), the daily achievements aren't working either. Something that has actually been quite interesting is the fact that, say I have two eggs on a timer of about four hours, said eggs don't actually show the timer but instead show a small caption beneath them that says "No Connection..."
I've already tried rebooting my device and uninstalling the application, but that doesn't actually help.
Any suggestions?
(I'm still extremely new to these forums, so I apologise in advance if I'm positing this in the wrong place.)
