I have a Roku TV and the streaming app's channel guide only shows what is playing currently. is there a way to see what is next like on ALL other guides?
While I don't currently use the Spectrum TV app and cannot test this, I used to use it back when I still had tv service on a couple of Roku TVs. It seems like I could scroll to the right to see what is on next. Are you not able to press the right arrow button on the Roku TV remote to scroll the guide?
You have to use the Roku remote "Back" button and then choose Guide from the list presented (Live TV, Guide, My Library, On Demand, Video store).
