Describe the bug

I am trying to upgrade my project from amplify 1 to amplify 2. The project is already live running on version 1, so my config files should be correct, at least for version 1. After upgrading to version 2, I am not able to sign in anymore with web UI, when the function is called, the browser tab opens and immediately closes again with a CodeValidationException:

I also tried starting a fresh new project from scratch, following the documentation, but with the same result. I am not using amplify (or the cli), but a Cognito User Pool without an Identity Pool.

Reproduction steps (if applicable)

Code Snippet

override fun onCreate(savedInstanceState: Bundle?) {
  binding.fab.setOnClickListener {view ->
      Amplify.Auth.signInWithWebUI(
          this,
          { Log.i("MyAmplifyApp", "Signin OK = $it") },
          { Log.e("MyAmplifyApp", "Signin failed", it) }
        )
    }

    try {
        Amplify.addPlugin(AndroidLoggingPlugin(LogLevel.VERBOSE))
        Amplify.addPlugin(AWSCognitoAuthPlugin())
        Amplify.configure(applicationContext)
        Log.i("MyAmplifyApp", "Initialized Amplify")
    } catch (error: AmplifyException) {
        Log.e("MyAmplifyApp", "Could not initialize Amplify", error)
    }
}
