Hey everyone - Thank you for the feedback.
I reset my device through the reset option from the menu, ran all available updates & still no luck. In addition I am now experiencing an issue where every time I power off the device, when I turn it back on the language is set to Chinese & I have to figure out how to switch it back to English. To answer some of the questions above:
1. My IPTV provider provides each user with their own M3U url that allows for custom programming of what channels each user wants. That is what I meant by "custom" URL. I tried both HTTP & HTTPS and was meant with the same result.
2. I also downloaded my M3U file and attempted to run it from there and was met with the same result.
3. I can run the URL or the file from the VLC app that is preloaded on the device without any issues; however, VLC is not very intuitive. Also having to use VLC defeats the functionality of the device, shortcut buttons on the remote etc.
4. I emailed support almost a week ago & I've heard nothing back which is a bit concerning.
5. My IPTV provide doesn't provide anything XC so I don't even know where I would star with that.
I attached a picture of my build version etc
