Hey, So over the last couple of says someone has been trying to airplay to my AppleTV. It appears onscreen with a four digit code - interrupting whatever I'm watching. Its happening more and more. Network is password protected, AppleTV is connected to it, Network interface page shows the devices on the network (my MacBook, iPad, iPhone, AppleTV and my other half iPhone, and MacBook). I just don't know how its happened, all I know its appears as "Caroline's iPhone" Any idea?
