Already Logged in?

[programmermattsrum]

Is there a way to see if you are already logged into google with this plugin? I have searched everywhere and can't seem to find a way.

see I have the same problem

[thientvimo]

this is error I
SignInException: DefaultInstance already created. Cannot change configuration after creation.
at Google.GoogleSignIn.set_Configuration

then you can add this code when create new google Configuration, that fixed my issue
if(GoogleSignIn.Configuration == null)
{
GoogleSignIn.Configuration = configuration;
GoogleSignIn.Configuration.UseGameSignIn = false;
}
