I don't watch sports and I dont have kids so I would like to be able to personalize the App Bar by removing Game Finder/Sports and YouTubeKids plus add the Apps I would prefer on the App Bar.
No, it is a preset designation. The apps available on there are the apps available on Dish. Cannot add more until Dish contracts them, and gets approval from the company. This is mainly because they are a TV provider and not an app service, like a ROKU, and they offer the apps they do already as a courtesy.
