Here you can see the main page of this app. Instead of add playlist on IPTV extreme website, you can add M3u list directly by click on Three dot button on the top right corner and choose Playlists option.
To add your M3u list please choose File or link to playlist option. My recommendation is to add m3u link instead of the file.
On the Playlist Name section, you can enter any name. Paste your m3u link on the playlist link or select file section. Click OK. You will get a message ” New playlist is added successfully“
Back to the main menu and wait for channels loading, it will take a minute.
With IPTV Extreme the channel sorted by country, this app have the Favorites folder, search button and support EPG and logo for each channel.
