I am working on adding In-App purchases to my app.
I am able to receive the productsRequest:didReceiveResponse
method, and receive the array of products
Hit with the same problem, i reset my device, cross verified the identifiers, re-installed the app. Also thought the problem was, because I had changed the reference and the description of the products. In reality, I feel it is because my test user had got locked as multiple people where using the same account, and it is a possibility that the password validation failed multiple times. So I re-created another test user and in-app purchasing is back to working. Hope this helps. I was totally stumped with this error.
