Hi Apple Devs,
We are having trouble getting subscription purchases to work in sandbox. We have sandbox set up with the right account and configuration, but the first subscription we submitted is still pending review. It seems that we cannot test the purchase flow until it has actually been approved. That is, attempting to upgrade your subscription leads to an "invalid product ID error", presumably because the product is not "ready for sale". Am I misunderstanding how subscriptions are supposed to be tested and reviewed?
Thank you!
