My APPLE ID is NOT working properly. I am frustrated beyond belief I have tried time and time again to change my apple ID and it keeps reverting back to my original ID!! I even set up a new email to try to submit a new id and it still does not work

To change your Apple ID, follow these steps:

1. Go to My Apple ID (appleid.apple.com), click "Manage your Apple ID", and sign in.
2. If you have two-step verification turned on, you'll be asked to send a verification code to the trusted device associated with your Apple ID. If you are unable to receive messages at your trusted device, follow the guidelines for what to do if you can't sign in with two-step verification.
3. In the "Apple ID and Primary Email Address section," click Edit.
4. Enter the email address you want to use, then click Save Changes. Apple will send a verification email to that address.
5. Open the email from Apple, then click Verify Now in the email.
6. When the My Apple ID page opens, sign in with your renamed Apple ID.
7. If you have two-step verification turned on, you'll be asked to send a verification code to the trusted device associated with your Apple ID.

After you see a message indicating that verification is complete, remember to update all of the stores and services that you use with your Apple ID.

It's doing that because you have content on the phone obtained with the old ID. All Apps are FOREVER tied to the ID used to obtain them, & they can only be updated using that ID, & cannot be transferred to a new ID.

The ONLY fix is to delete the content & re-purchase with your new ID.

You could also "try" contacting iTunes support, explain the situation, & ask that they add this content to the download queue of your new ID. If they agree, then just delete the old content.

BTW: Everything is working properly, & as designed.
