Quite weird as I'm on iDevice too and I'm not currently having these issues. I'll just hope the problems will be fixed for everyone else aswell!
This is actually an iOS-wide issue that was recently discovered. We've put a fix on our end with our games but it still affects many other apps/iOS itself. Apple has already released a statement that they will fix it in an upcoming update. Beyond that, please refrain from posting specific details to the bug on these forums or encouraging others to use them. Doing either will result in a forum ban.
Good thing I copy and pasted that removed message for use later... Kidding... Apple sure is dickered up pretty bad today compared to normal...
I stand partially corrected. Silly apple. But I still say don't update until others have reported all the update issues. I'm on I phone with old iOS and no issues. Other than no event page. No specifics mentioned I believe there other than grateful I have a working version
