I have a Roku Ultra LT and if I am following what you all want to do, here are the steps.
Go to the Roku Home Screen.
Press the remote’s right arrow. The first streaming app should be highlighted. Now arrow to the app you want to remove.
Press the remote’s * button. A new menu will come up. In this menu is a Remove Channel choice. Arrow to that choice and press the OK button.
In this same menu, there is a Move Channel choice. This allows you to move the channels around to your liking.
Again, I hope this is what you all want to do. I’m not sure if the Roku TV works this way.
That is indeed how to arrange the apps on the Home Screen. However, the question relates to a feature related to a Live TV Channel Guide that was announced by Roku:
Customizing the Live TV Channel Guide – The Live TV Channel Guide makes it easy to discover and watch free live TV on your Roku device, and includes more than 165+ live options from The Roku Channel. With Roku OS 10, you can now hide individual channels as well as add channels to a favorites list within the Live TV Channel Guide. Quickly switch between guide views to see your favorites, recently visited, or all channels.
However, the only options I can find for the Live TV Channel Guide in The Roku Channel is for Recents and All Channels, while the annoucement also mentiones Favorites.. That's the issue. I'm still hoping @RokuDanny-R will weigh in.
