Logged into icloud on PC but cant access settings or find my phone
I am trying to deactivate my old phone. It has been erased/restored. According to the sign in screen on the phone, it needs to be deactivated from my icloud and find my phone. I have signed into my account online on my PC, however nothing happens when I click any of the icons on the screen. I can't go into settings or find my iphone, or any of the others. Once I click an icon, after a long pause, I get an error message that says cannot load "settings", there was a problem loading the application. Thanks for your help
iPhone 6, iOS 8.4
