Re: Can't link my new device

I am having the same issue. It looks like the latest update has broke the ability to use a guest account and connect it with facebook. The error we are receiving is actually:

Error [9] The target player must be an adult in order to link accounts.

You can recreate this error by using a device (IOS for example do not log into game center), start up the game and use the facebook connection option. You will receive the exact error of the original poster. This recently changed in the latest update as it had always worked before.
