I have in-app purchases working in my production app, and I\'m adding a new item for sale.
However, I can not test a new in-app purchase in the sandbox environment.
OK. I've figured this out. It was my test account. Since I was taking the account and logging in through Settings->App Store, I was registering each with credit card and email notification. I used an old account that created before but hadn't "activated", and it worked. So, the key was to not log in through the Settings->Store - stay logged out. And then log in with a test account that was only created on iTunes Connect, but never activated.
