Don't know if i log out the game too long ? now the game no longer able to go online and my iPad mini warn me that the game needs to be updated to prevent slow down on my device.:(

You cannot play this game offline. You will need to be connected to wifi to play. (or play on cellular service if you have that option)

Other game works fine but not this one, keep asking for internet connection. :(
Does i need to uninstall then reinstall ?
