Microsoft-authentication-library-for-dotnet: [Bug] GetAccountAsync and GetAccountsAsync do not return any accounts for Microsoft Azure Government account on Xamarin.Android

[bemartin]

Logs and Network traces
This issue happens with or without broker. Captured logs for a session with broker were sent with Incident ID E8E523P5

Which Version of MSAL are you using ?
MSAL 4.23.0, MSAL 4.24.0

Platform
Xamarin android (accounts do get returned for Xamarin iOS so it seems to be isolated to Android)

What authentication flow has the issue?

• Desktop / Mobile
  
  
  
  • [X] Interactive
  
  
  • [ ] Integrated Windows Auth
  
  
  • [ ] Username Password
  
  
  • [ ] Device code flow (browserless)
  
  
• Web App
  
  
  
  • [ ] Authorization code
  
  
  • [ ] OBO
  
  
• Daemon App
  
  
  
  • [ ] Service to Service calls
  
  

Other? - please describe;

Is this a new or existing app?
This is an existing app but we are currently working on adding support for Microsoft Azure Government accounts

Repro
Code to initialize the ClientApplication

var applicationOptions = new PublicClientApplicationOptions
{
    AadAuthorityAudience = AadAuthorityAudience.AzureAdMultipleOrgs,
    ClientId = "client_id",
    RedirectUri = redirectUri,
};
var applicationBuilder = PublicClientApplicationBuilder
    .CreateWithApplicationOptions(applicationOptions)
    .WithParentActivityOrWindow(this);

ClientApplication = applicationBuilder
    .WithBroker(true)
    .WithAuthority("https://login.microsoftonline.us", "organizations")
    .Build();

Code to acquire token interactively

return await ClientApplication
    .AcquireTokenInteractive(scopes)
    .WithAuthority("https://login.microsoftonline.us", tenantId)
    .WithUseEmbeddedWebView(true)
    .ExecuteAsync();

Code to get account:

return await ClientApplication
    .GetAccountAsync(accountIdentifier)
    .ConfigureAwait(false);

Expected behavior
When doing a silent sign in at app launch, we attempt to get the account object from the MSAL cache for the saved (in our app's user settings) account identifier. GetAccountAsync should return the account since the user has already obtained a token for that account.

Actual behavior
Both GetAccountAsync and GetAccountsAsync do not return any account

Possible Solution
No suggestions as it works for Xamarin iOS

@bemartin you confirm that this is the same without broker?

@bemartin Benoit Martin (AAPT) FTE you confirm that this is the same without broker?

Yes, I am observing the same behavior with or without broker

The issue suddenly went away. I suspect that some bug in my code was getting the cache in a state where it was not finding accounts for the US Gov cloud since I was making lots of changes to allow switching between Public and US Gov clouds.
I apologize for the false bug report. I will re-open it if I ever figure out why this was happening and can have a repro that would warrant some type of change on the MSAL side
