Basically, some of the sections in the were renamed and two menu items were moved out from "Live TV". Here are the additional details:
The On Demand section is now labeled Browse. Don’t worry, all your favorite On Demand content still lives in this section. The only change is that we have added Live TV here as well. So, for example, if you’re looking for Kids shows, the Kids section under Browse is now your one-stop-shop for both On Demand and Live options.
The Kids, Sports and Movies menus have disappeared from the Live TV section. Don’t worry, On Now and Upcoming programs on Live TV can now be found in the Browse sections for Kids, Sports and Movies.
