I suggest making sure that your Apple ID country or region is set to the United States using the steps in this support article: Change your Apple ID country or region , specifically:
What to do before changing your country or region
- Spend any store credit remaining on your Apple ID. You must also wait for any pending store credit refunds to process before you can change your country or region.
- Cancel any subscriptions and wait for any memberships, pre-orders, iTunes movie rentals, or Season Passes to complete.
- Update your payment method. For example, only German credit cards can be used to buy content from the German iTunes Store, iBooks Store, and App Store. Have your credit or debit card for your new country on hand.
- Back up your iPhone, iPad, or iPod touch to iTunes. You might need to temporarily downgrade your iCloud storage until you switch to the new country.
If you're a part of a Family Sharing group, you might not be able to change your country or region. Learn how to leave a Family Sharing group.
You might not be able to redownload some of your purchases from your original country or region.
