If you have a subscription with two different possible lengths in your iOS app, and the user, who has purchased the shorter subscription, decides to purchase the longer subscription instead, they get prompted with this dialog:
Tapping Settings takes the user to the App Store app and opens the page where they can manage their subscriptions. Most probably Cocoa simply uses a custom scheme URL (e.g. appstore://pages/subscriptions) to achieve this.
What is this URL? Is there another way to open the subscriptions page in the App Store app programmatically?
