I used to test my macOS app with a Storekit file, and now wanted to test it in the Sandbox environment. I have removed the storekit configuration file from my schema options. However, even after removing it and have IAP setup on App Store Connect (still rejected), I cannot get the app to use the sandbox environment. Things I have done: Set the schema options StoreKit configuration to none. In the Mac App Store, login the sandbox account as my test user. Clean my build folder. Removed all derived data from Xcode. Run the app from Xcode or from the binary directly. Regardless what I do, when I'm trying to purchase, I still see the purchase sheet says "Xcode" from the top left (instead of Environment: Sandbox).
