I know Apple support 2 links for IAP, one for debug one for release, I built my app to my device on debug mode, and used https://buy.itunes.apple.com/verifyReceipt to buy a IAP product, but the device always show me a alert with [Environment:Sandbox].
what I want to know is: can I test iap through true store(https://buy.itunes.apple.com/verifyReceipt) not sandbox store.
I think you can not test it through the actual appstore on the debug mode.
