Sorry, let me try again. What I am talking about here is the IPTV channels section. I have loaded an m3u playlist there. When I go into IPTV Channels, unlike the portals where a a channel is only played when I click its name,, aa soon as I select a channel, it is automatically played. This is not convenient when you have more than one hundred or even several hundred channels and you want to browse through the list and select the channel you want to play.
I hope this is clear.
I was told to "go to Settings > Portal". I answered that I had no suc entry with the name Portal in my settings. Then you advised me to "enter Settings / Interface and set: 1. Start Page in Main menu; 2. Stand by mode in Deep.". I did that and the situation is unchanged in that I don't have a "Portal" button under Settings.
