Everything working fine except when I mirror my iPhone to any of my Roku TVs and use my Spectrum cable live TV app…..only some channels show up on the TV……many do not……CNBC does not mirror but ESPN does! No error msg…..just on going “thinking”…. Internet connection good…..everything mirrors except many channels on my cable tv app…..my non Roku TV has no issue w/the same TV app…….any ideas are appreciated…….
