Is it possible to test AppTransact… | Apple Developer Forums

Is it possible to test AppTransaction.originalAppVersion using TestFlight?

I would like to determine which app version the user first downloaded. For that, I'm using StoreKit and the originalAppVersion property of AppTransaction:

let verificationResult = try await AppTransaction.shared
switch verificationResult {
  case .verified(let appTransaction):
    return "\(appTransaction.originalAppVersion) (\(appTransaction.environment.rawValue))"
  case .unverified(let appTransaction, let verificationError):
  &#x2F;&#x2F; The app transaction didn&#039;t pass StoreKit&#039;s verification.

The code runs fine, but always returns "1.0" for the app version and "Sandbox" for the environment. I tried debug/release builds and even pushed a build to TestFlight.

Is the only way to test this to push a new App Store version that should go live?
