I joined the OS X Public Beta Program a while back, and when I log in, I don't have the option to join the iOS public beta program. I've searched around and everyone says the same thing: Join or log in to Apple and I have the choice of the Yosemite or iOS public beta programs. I've only been able to join the Yosemite public beta and there is never an option for the iOS one. I've seen screenshots of the page showing both options. Anyone know why I don't have that option?
