Hi @topgun,
Unfortunately, we still don't have details on a change to be made for the CH + CH- button. As mentioned by JulieL, this is an expected behavior of the platform. That said, I take note of your interest in this improvement and will pass it on to the teams concerned.
A workaround that I can advise is to use the mini-guide function which also adjusts according to the program filter chosen. You can display it with the right directional arrow key on the remote control. Then scroll up or down the list and lastly use the middle button (Ok/Select) to change channels. You could therefore configure the guide filter so that it selects the "Free to me" filter, or even "Favourites", if you would like to use a custom channel list. This will allow you to see the programming being broadcast on other channels without having to change channels position while still maintaining a good view of the current live channel being viewed.
Another good tip to know is to configure the schedule guide filter to always select the same filter. For this you have to use the Helix button then select the gear on the right. Then select "Preferences" followed by "General" and finally change the "Default guide view" option to whatever filter you need.
