Redirect back to Android App Not working fully

[bradyguyc]

I built this example with .NET 10 preview and on android after authentication which is valid it pops up a dialog to select from apps.

https://github.com/Azure-Samples/ms-identity-ciam-dotnet-tutorial/tree/main/1-Authentication/2-sign-in-maui

The only changes I made to the sample are the client id. The updatemsal.ps1 is a script that updates the msal from appsetttings.json.

Using an older method for MSAL I don't see this problem. After I click sign in on this image it goes straight back to the app. This older method is using policy based method I believe.

         AuthenticationResult result = await PCAWrapperB2C.Instance.AcquireTokenInteractiveAsync(B2CConstants.Scopes);

private PCAWrapperB2C()
{
// Create PCA once. Make sure that all the config parameters below are passed
PCA = PublicClientApplicationBuilder
.Create(B2CConstants.ClientID)
.WithExperimentalFeatures() // this is for upcoming logger
.WithLogging(_logger)

                              .WithB2CAuthority(B2CConstants.AuthoritySignInSignUp)
                              .WithIosKeychainSecurityGroup(B2CConstants.IOSKeyChainGroup)
                              .WithRedirectUri(B2CConstants.RedirectUri)
                              .Build();

}
