My account is disabled for Media and Purchases on iPhone XR

Apple has a support article that explains what to do when an Apple Account is locked or disabled. Click on the following link: If your Apple Account is locked, not active, or disabled - Apple Support

See the following excerpt from the above support article:

If your Media & Purchases account has been disabled

If you see a message that says “Your Media & Purchases account has been disabled,” you might be able to request reactivation by tapping Continue right from the alert.

You can also request reactivation.

If the Chat and Call options at the bottom of the "request reactivation" link in my previous post

do not work, click on the following for other methods: Contact - Official Apple Support
