It is easy to assess free stable m3u files with World TV from google play. install, choose player; VLC, choose Language or country push play. You will have the file in the downloads folder that you can save and use anywhere VLC Player works. I've looked for hours... If you are using windows VLC list the playlist and search for the channel you are looking for, the list is long... Another good free android app is Local Now.
I hope this helps you find live channels.
