Cancelling subscriptions immediately

If your are changing to a subscription in a different country your account will have to be set to that country. You are--or will need to--change country settings. The support article Change your Apple ID country or region - Apple Support describes how to change your country setting on everything using your Apple ID, and the requirements and results of doing this.

Apple can stop a subscription immediately when you want to change your region. Contact Apple again:

Since they suggested a refund request, it sounds like they did not understand what you were trying to accomplish. Simply tell them that you want your subscription cancelled immediately because you need to change your region. You will need to cancel the subscription first on your end and then they cancel the remainder to allow you to change your region.

Subscriptions will continue until the expiration date. Canceling them just tells them not to renew after that date. To have it end before that date you need to contact Apple and explain you need it to end immediately.

Then that is new. For years we have been telling people to ask Apple and nobody has reported any problem doing it that way.
