My issue is complicated. I have a new Roku Ultra. My Panasonic Smart TV is connected to a cable box on HDMI 1. My Roku Ultra is connected to HDMI 2. I control both with a Logitech Harmony Touch remote. When I turn on the TV initially everything works as it should. I can change channels, check my DVR, check my program listings, etc. When I use my remote to go to Roku, I first get a fish tank filling my screen. I can then hit home and the Roku home page opens. I can then stream from Amazon Video, Utube, etc. When done, I hit the TV icon on my remote screen and I then return to my TV. The problem arises when I try to change channels, look at my DVR or do any other activity. When that happens, I am automatically returned to Roku on HDMI 2. Apparently, my Roku Ultra does not know to stop operating when I return to my TV on HDMI 1 after using it. This was not a problem on my Roku stick that I had previously. How do fix this?
