Apple One - Family member's existing subscriptions
I've been looking at upgrading to Apple One Premier for me & my girlfriend. She currently has an Apple Music subscription that she recently just renewed this month (using the annual option).
If I upgrade to Apple One Premier & share it with her, what will happen to her Music subscription that she just renewed? Will she get refunded? Do I need to wait until that subscription expires before buying/adding her to Apple One Premier so she doesn't lose out on what she just paid?
Thanks in advance for any help.
