Some stations in epg not populating

Hello!

Using IPTV M3U and XML links. Most of the stations populate.

There are 3 that are not. Support at the IPTV says they are getting the data. Could this be a Channels issue?

Trying to learn how to troubleshoot this.

Thanks!

The xml file you are passing to channels is a simple text file, you can view it in a browser or download it. If you look in it do you see the guide data in the xml file?
