Ok perhaps someone has set this up before? I am trying to narrow down the reasons why this IAP process is not working on Apples store!!
This is a test app which is running on iOS but as you can see from the error message, the purchase part is not.
Are the events correct? I Get a store is available, but no store listing is returned, I don't get a succeed or fail message, just the error you can see when I click to buy.
