My son wants to play on his tablet. It’s an IOS. He has his own Facebook account and Game Center account. When we download the app, it logs in to my farm. How can we stop this? He has his own unique I’d for apps and Facebook. Ive tried deleting, reinstalling. When I say connect with Facebook, it says the farm is connected to another account. Login with that account. We don’t want to do that. We want a new farm. Please help me.
