Verifying account information - session timed out
I am having this problem on both my new iPhone 5 and my iPad 2 since upgrading to iOS 6. It won't let me purchase apps, wanting me to verify my payment info. I'm happy to do this, except it keeps telling me my session has timed out.
I have tried going into Settings App > iTunes & App Stores > tap where it says your Apple ID > tap "Sign Out" > Sign back in, and verify the account info, but I keep getting the session has timed out error. I have also turned off and restarted my devices and then related the above steps. I have also tried signing out and back in from the App Store app on both devices.
Anyone have insight into or a solution for this problem?
