Auth Facebook does not work on Android

Hi!
On Auth Facebook Android is not set muttability flag for pending intent. Handling activity result then ends up in exception.

Java.Lang.IllegalArgumentException: 'app.name: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

Hi,

for sign in with Facebook Plugin.Firebase.Auth.Facebook just calls the methods of FirebaseAuth:

Plugin.Firebase/src/Auth.Facebook/Platforms/Android/FirebaseAuthFacebookImplementation.cs

Line 30 in 34f6f5b

public async Task<IFirebaseUser> SignInWithFacebookAsync()

That means creating the PendingIntent happens inside the Xamarin.Facebook.Android sdk and there is no way for Plugin.Firebase to set FLAG_IMMUTABLE or FLAG_MUTABLE. Furhtermore the sdk was last updated at 19.10.2021...you could create an issue on their repo and cross fingers someone responses.

@TobiasBuchholz It looks like, they dont have intention to fix it soon (xamarin/FacebookComponents#237 (comment)). Can we use fixed library for login like https://www.nuget.org/packages/Anjo.Android.Facebook/ in this plugin?

It would help a lot. Thanks.

Any update on this? Or has someone workaround? This is still major issue for us.
