Based on this site https://support.apple.com/en-us/HT202039 the subscription can be cancelled & re-subscribe by user on iPhone devices. I'm asking for the payment lifecycle included with subscription status when subscription is canceled, re-subscribe, or subscription is EXPIRED. Please explain billing lifecycle to our bank account based on subscription status. Thankyou.
