Hello, I'm currently trying to test billing on my app, since we want to do something different if the app is paid, in trial or lapsed, I am in sandbox and have set up a new Subscription Pricing on the app page that should charge 1 dolar a month, but when I go to choose that new subscription option for a test merchant the option appears with "US$1.00 per month" crossed off and the word "Free" under the price. Sure enough if I choose this option and I check the BillingInfo API it returns the same that was returned when the app had the free subscription. How could I make this actually "charge" the sandbox merchant? How can I simulate the merchant having a credit card vs not having one, or vs having it declined. I also tried pressing the 30 day free trial button but isInTrial kept being false even then, how could I test a Merchant in trial?
Thanks, Diego.
