When you try to change your county, you might see one of these messages:

• You have an active iTunes Match subscription; you must cancel it before you can change stores.
• You have at least one incomplete pass. Passes must be complete before you can change stores.
• You have rentals that have not expired; they must expire before you can change stores.
• You have a store credit balance; you must spend your balance before you can change stores.
• You have one or more pending store credit refunds. You must wait a few hours for these to complete before you can change stores.
• You are part of a family. You must leave the family before you change stores.
