Won't stay signed in to app store , Invalid Security Code?
Hi
Have a new iPhone 5s. When accessing the app store it keeps prompting me to sign in. The sign in only lasts 10 minutes or so.
Also when I go to settings, iCloud, account, payment information it reads that security code is required but after entering the valid code and pushing the done it states it is invalid. It is not invalid. It works on my desktop iTunes.
Any suggestions?
