Unable to play content on the Roku channel with Roku Ultra 4800X
I have a new LG Smart TV with my old Roku Ultra device connected by HDMI via both TV and Roku on WIFI. My problem is it won't play anything from the Roku Channel App on the Roku device but will play everything on the other apps installed on the Roku device. I'll click on the Roku Channel App, then choose the movie/tv watch now icon, the screen will go black for a couple seconds then it'll say 13% for about a minute then it will go back to the menu. All other streaming apps on the Roku device works fine and the LG apps works fine. Roku App is not available on the LG so I have to have the Roku device to watch Roku. Any suggestions on how to get this to work would be appreciated, I don't know if its a setting on the LG TV or the Roku Device or a combination of both.
