Cannot test macOS app in Sandbox environment

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).

App store has approved my IAP but still cannot get the sandbox environment working.

Please file a Feedback report using Feedback Assistant, then post the number here.
