Has anyone run in to this issue before? I've just moved to the 5S, just wanted to install some apps and I am unable to Verify my Identity due to being unable to select my Trusted Device from the Trusted Devices screen. I see my devices, but if I press one nothing happens, if I click next it wants a device to be selected. I've tried sighing out/in to the App Store, and removing/adding the Trusted Device via my Apple ID. Now I'm stuck 🙂
