SS IPTV

Hello guys,

I just bought a Philips smart TV I am doing the typical process getting the CODE from the TV entering it on my laptop adding the normal playlist ending with this m3u code, I am saving it everything is fine. I have loaded more than 10 different playlists I can see them on my TV but ALL the channels are giving me "Unable to play: *channel name* ALL of them. I must doing something wrong but no one has a solution for this as I saw that someone else posted the same thing but no one answered.
Moreover, the 5-6 channels that are already installed in SS IPTV in the first purple section "Open TV" are playing normal. What should I change?
Please enlighten me.

Thank you so much in advance.

Did you make sure that channels work? For example in VLC on PC or whatever. Well, on the internet you can find loads of unworking playlists, maybe that's the reason why your different playlists were not working.
