If your app needs to offer users the ability to buy multiple subscriptions — for example, to subscribe to more than one channel in a streaming app — you can add these subscriptions to different groups. Users who buy subscriptions in multiple groups will be billed separately for each subscription. Keep in mind that if a user moves from one subscription group to another, their renewal date will change and their days of paid service will reset. Multiple subscription groups are not recommended for apps in which users would expect to have a single active subscription.
Could you please confirm that user can have more than one active subscription and will be charged for each separately?
Could some one please send an example from iOS settings - Subscriptions how does it look when user has several active subscriptions and how he can cancel them?
