Use an IPTV App?

Yes - you can use most IPTV Apps to watch your favorite channels.  When you subscribe and Bookmark channels, we allow you access to those channels using a well known format - M3U.  So any device that understands the M3U format can access our service, download your bookmarks and let you watch.

These instructions show you to watch your channels on Kodi.  But just use the same URL ( <your address>) and your IPTV client can access your channels.
