NHK World channels broken on stream app

Hello, I posted this in another section of the xfinity Community Forum. No one from xfinity responded so I am trying again on the Stream App forum section. Here is my original post: https://forums.xfinity.com/t5/Xfinity-Stream-Website/NHK-World-broken-on-streaming-app/m-p/3407137

Basically, NHK World has not worked on either of my 2 TV's running the stream app for over a month now. I would appreciate some attention to this. I pay xfinity for this service and am not getting any support or the channels I am paying for.

One TV is an LG and the other a Samsung. The NHK channels don't work on either but in slightly diffferent ways. I have uninstalled and then reinstalled the app on both TV's without luck.

I think this is could be a problem on xfinity's side as it happened a few times in the past couple of years but the channels would begin working again without anything being done by me. 

Could someone from xfinity please address this?

Thanks
