It is because you're using a newer version of the package. Downgrade to 3.7.2 or check the docs here for the updated implementation.

Could you help me?
This is my implementation, but in Release Mode dosen´t work
private async void LoginBtnTappedAsync(object obj) { IsLoggingIn = true; var client = new AppAuth(Constants.FireBaseConfig); try { var userCredential = await client.SignInWithEmailAndPasswordAsync(userName, userPassword); string token = await userCredential.User.GetIdTokenAsync(); StorageService.RestoreFileFromCloud(userName, token); Preferences.Set("UserName", userName); Preferences.Set("Password", userPassword); await Shell.Current.GoToAsync(nameof(HomePage)); } catch (Exception ex) { await App.Current.MainPage.DisplayAlert("Alert", "Ocurrió un error al acceder! Intentalo Nuevamente", "OK"); } finally { IsLoggingIn = false; } }I need support but i cant found documentation
