I have the same problem. I watch OTA channels, and since those other channels appeared on the channel guide, the channel listings takes a long time to appear. Let us have the choice of which channels to keep or not keep, along with the regular OTA channels.
I have the same issue except I am using the "Antenna" channel. I dont want streaming channels on my "Antenna". I usually only watch 2 channels at a time on the antenna and switch back and forth but now I cant even so that because the previous channel button just randomly jumps forward through the channel list till it gets to the end and then does nothing.
I have the same problem. I use my TCL Series 3 Roku TV to watch 2 OTA channels. The remote has no direct channel input capability, but since I bought it 35 days ago, my home screen showed an 'Antenna' tile, and once there I was able to pull up a channel guide of just OTA channels and use the 'instant replay' button to toggle between my favorites. Suddenly this evening the 'Antenna' tile changed to 'Live TV', which was formerly contained within the ROKU CHANNEL. Now I have to page through this garbage, the instant replay button no longer works, the ability to set favorites no longer works, and I am ready to throw this 35 day old TV in the garbage. What a lack of respect for the customer! I will never buy another ROKU or TCL product. AARRGGHHH!
