Changing region with Apple One subscription and family sharing
We moved to the US from Europe and I need to change region on the App Store to have access to some apps. I've cancelled my subscriptions (Apple One and Netflix) as per the guidance on how to change and I'm waiting for the end of the subscription period for both.
However, I don't want to loose the backups and photos stored on iCloud. How can I preserve the data in iCloud while changing region?
