Hi, I understand that Apple takes a 30% commission fee for all in-app purchases and offers a drop to 15% if the user subscribes for over 12 months. Is the 12-month clock for a specific subscription group tied to the Apple account? Suppose a user logs into user account A and subscribes through Apple account X for 11 months, and logs into user account B and subscribes through the same Apple account X for another month. Does it count as a 12-month subscription eligible for a commission drop?
