Azure Active Directory Single Sign Out - Xamarin iOS

Hi I am using Auth0.OidcClient.IOS 3.3.7 and Auth0.OidcClient.AndroidX 3.2.7 and an Azure Active Directory enterprise connection.

For these AAD users, single sign out works correct on Android, but fails to sign them out of AAD on iOS. Here is my call to logout.

        public async Task<BrowserResultType> LogoutAsync(string logout_hint)
            return await Auth0Client.LogoutAsync(true, new { logout_hint });

Federated is set to true, but its failing to perform the federated logout.
