So here I am doing my daily battle with Roku channel changing. All I want to do is watch OTA and then switch to a Roku streaming selection using the 'Previous' button. I get a grey screen and audio on RS when changing from OTA but a normal screen when going from RS to OTA. I get a glimpse of video at the switch but then grey screen and audio. Sometimes it takes 5 or 6 times back and forth before it grabs. Now I have to choose the RS channel, go to 'Home' then back to 'Live TV' for the RS feed. The next move between the two starts the issue all over again. The same no matter the selection set up. 11.0.0 Build 4193-88. Look for 'improvements' coming to you soon.
