TV main interface disappeared

Recently, when I launch TV (11.0) on my Mac, there's no screen/startup interface. Instead, the app shows in top menu bar as the active app, with Edit, Connection, Extra, Windows & Help nav  menu links, but there's no interface. Looked through all the menu commands, rebooted w no luck. 

How do get the interface back, to see the numbers I give out for connecting to my Mac?
