We're currently encountering an issue between Supercell games and Game Center that prevents most iOS users from switching accounts on the same device. While we don't support multiple games on the same handset, we know that many players use this function.

On behalf of the team, I would like to apologise for the disruption this causes to your gaming experience. Our team will work closely together with Apple to get this fixed as soon as possible. 

Meanwhile, please note that switching villages on iOS6.x or lower is not possible due to security precautions. You need to update iOS or upgrade your device to enable this function.
