We have been using an app called blocklauncher. And it has been working fine till a couple days ago, there is usually a M button in bottom right corner, and it disappeared. Either it will let me sigh into world and the M button is gone. Or it says error cannot connect to server and it will have the M button...any help??? I've tried shutting down app and system, restarting, reinstalling, upgrading idk wat else to do
