I'm having an issue recently that I didn't seem to run into before with my iOS sandbox testers and In-App Purchases. I've done the following:
- Create a new sandbox tester that hasn't been used before. Assign to United States.
- Log out of all iTunes accounts on the device.
- Open app and go through In-App Purchase flow.
- Log in via the new itunes sandbox account.
This usually works for me. But now I'm getting a prompt that says "Payment Information Required - To subscribe, add a new payment method. You'll only be charged when your trial ends. [Environment: Sandbox]".
I've seen similar SO questions that mention that they created the sandbox user in the wrong country or had previously registered a valid existing account. None of these are applicable in my situation.
Anyone else running into this right now? Any suggestions?
