We are developing an app that uses the non-renewing subscription IAP model. While testing the subscription purchase process in the sandbox, we are seeing two messages with ‘buy’ buttons pop up.
The first message is displayed with the product information: “Do you want to buy one subscription for $xx.xx?”
After you click ‘buy’ for the first message, a second message (with another buy button) is displayed: “You’ve already purchased this subscription. Tap Buy to renew or extend it.”
Is this normal iTunes/sandbox behavior for re-purchasing non-renewing subscriptions after they have expired? Does iTunes require you to tap a ‘buy’ button twice?
