I have an app that has been approved by Apple's review team and includes a renewable monthly subscription, which has also been approved. However, when testing the app with a sandbox account on a real device, I am encountering an issue.
Within the app, when trying to fetch the subscription using the product ID to display it and allow the user to subscribe, I am unable to retrieve the subscription data, even though I am providing the correct ID and using a sandbox user account on a real device.
I would like to request support to understand and resolve this issue. Is there any additional configuration or procedure I should follow to ensure that when fetching the subscription using the product ID, I receive the subscription data to display and allow the user to subscribe?
