Are existing Pre-paid subscriptions refunded when Apple One is added?
If an Apple TV+ subscription is pre-paid for say the next 16 months, and I add Apple One that includes Apple TV+, how much is refunded? Are the next 16 months refunded? Is the next month refunded on a pro-rata basis, and the remaining 15 months fully refunded? Or is only the next month refunded on a pro-rata basis, while the remaining 15 months are just lost value?
