Hi, I am using a m3u file on smart IPTV app on Samsung tv but I am getting a message 'check playlist url!' And there are no channels displayed. the file is working fine on vlc player where all the channels are visible. I am lost as to what needs to be done on the smat IPTV app. i have uploaded the m3u file on siptv.eu website which also showed that all channels/groups are successfully uploaded. Any help from experts would be much appreciated. Thanks in advance.
