Same for me and it is So frustrating to have to scan through so many channels to get to the one I want. Per other posts I tried going to Settings> TV Inputs> Antenna TV> and there is No Favorites to turn On or Off. Please ROKU either put back the automatic Favorites or give us the option to turn it back On.
Same problem TCL model 55S405. Software 9.4.0 build 4190-30. No favorites populated in the channel guide since the rollout of new guide with streaming channels . I successfully removed the streaming channels but the favorites did not populate as before. Atlanta is a big OTA market so there are over 100 channels to scroll through. With no number keys on the remote having favorites grouped together is important, I can’t figure out how to insert a picture but the guide starts with channel 2.1 and scrolls to 69.5 with a hundred or so channels in between,.
As stated in my previous posts, can you please provide us the following information: -Roku TV brand and device model -serial number -device ID -software OS/version (these can all be found in Settings > System > About) -when did you start seeing this issue occur?
With more information we will be able to assist you further.
