I updated to the PB today, and I have run in to an issue in iTunes. It says that it needed to log me out to maintain security, but when it asks me to sign in again it gives me this: "A verification code is required in addition to your password. A notification with instructions for signing in has been sent to your other devices." The problem is I don't get a notification on my phone. It is running iOS 9, and everything other than iTunes seems to be fine. My iCloud account is signed in and working everywhere else on both my devices. Anyone else see something like this?
