We are a group of 10 friends using the same device and Apple ID, but each of us has a different account within the same app. We want to purchase the same auto-renewable monthly subscription plan, each using our own app credentials.
The issue: after the first person subscribes, the next user (with a different in-app account) is unable to buy the same plan—it shows "already subscribed" and only allows access after the next billing cycle.
We don’t mind the auto-renewal being charged each month by a different person. We just want each app account to have access to the same package independently, for 1 month each.
How can we achieve this without changing the Apple ID or device?
