How to sign back into my iTunes

Click on this link to find out how to 'Sign in with your Apple ID' --> https://support.apple.com/HT201762 "After you log in, you can use the App Store, iCloud, iMessage, Apple Music, Apple TV+, and more."

There are many error messages related to items being disabled and similar, but I have never, ever seen one saying "locked out of iTunes". it helps to be precise when quoting messages here or else we are having to guess.

If you see a message that says "Your account has been disabled in the App Store and iTunes" click here ➞ https://support.apple.com/HT208856
