Mirror: Cannot declare SyncList

Hey guys,

Just started poking around multiplayer and Mirror. So far it’s great!

I am struggling to understand why I am unable to declare a SyncList.

public class GameManager : NetworkBehaviour
{

    public SyncList<bool> connectedPlayers = new SyncList<bool>();

}

Any idea what I might be doing wrong here? Not sure what info is useful to provide, so apologies if it’s lacking, will add whatever is requested!
