I am implementing auto-renewable subscriptions in iOS and want to be able to test the scenario where the user cancels the subscription but I am unable to do so because when I try to manage subscriptions with the sandbox account the app store wants me to associate a payment method with the sandbox account but in my experience once I do that the sandbox account is no longer valid.
Is it even possible to test cancellations or do I just blindly code for cancellations? I have search high and low and have not found anyone who has been able to manage subscriptions in a sandboxed environment.
