When I first loaded the solution, I got a brown banner at the top that said "one or more projects have changes that cannot be resolved by the project manager. Reload projects" - the "Todo.Uno.Mobile" project had errors related to missing targets.

Clicking the "Reload projects" solved the problem. Is this something we can do for the user, or do I need to instruct the user to do this?

Solved the MSAL issues (including the TFM stuff) by simplifying the PublicClientApplicationBuilder to the following, and switching to Uno.WinUI.MSAL:

#if ANDROID || IOS
        string redirectUri = $"msal{Constants.ApplicationId}://auth";
#else
        string redirectUri = "https://login.microsoftonline.com/common/oauth2/nativeclient";
#endif
        _identityClient = PublicClientApplicationBuilder
            .Create(Constants.ApplicationId)
            .WithAuthority(AzureCloudInstance.AzurePublic, "common")
            .WithRedirectUri(redirectUri)
            .WithUnoHelpers()
            .Build();

New error during build:

My AndroidManifest.xml looks like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <application>
	  <activity android:name="microsoft.identity.client.BrowserTabActivity" android:configChanges="orientation|screenSize" android:exported="true">
		  <intent-filter>
			  <action android:name="android.intent.action.VIEW" />
			  <category android:name="android.intent.category.DEFAULT" />
			  <category android:name="android.intent.category.BROWSABLE" />
			  <data android:scheme="msal2160b3eb-9ce1-4d3a-abc0-d37a45cd2e59" android:host="auth" />
		  </intent-filter>
	  </activity>
  </application>
</manifest>

And MainActivity.Android.cs looks like this:

using Android.App;
using Android.Content;
using Android.Views;
using Microsoft.Identity.Client;

namespace TodoApp.Uno
{
    [Activity(
			MainLauncher = true,
			ConfigurationChanges = global::Uno.UI.ActivityHelper.AllConfigChanges,
			WindowSoftInputMode = SoftInput.AdjustPan | SoftInput.StateHidden
		)]
	public class MainActivity : Microsoft.UI.Xaml.ApplicationActivity
	{
		protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
		{
			base.OnActivityResult(requestCode, resultCode, data);
			AuthenticationContinuationHelper.SetAuthenticationContinuationEventArgs(requestCode, resultCode, data);
		}
	}
}

There doesn't seem to be a workaround for this at the moment, so just need to flag as known warning for the user

Yes, Uno.WinUI.MSAL is the main fix for getting auth to work. I'll send you the details
