I want to test in-app purchase in Sandbox environment but the SKProductsRequest method is returning invalidProductIdentifiers.
When I build the app on simulator or real device including the StoreKit config file, I'm able to see the products. But, when I test after excluding the config file or from the test flight build, I'm not able to see any products.
Can someone help, do we need to Sign up for Paid Apps Agreement with all the bank info and Tax forms even if we have to conduct the tests in Sandbox environment?
