Apple TV navigation not working

I just installed channels using a MacBook Pro and an Apple TV and using Locast as my source. If I go to the guide it only shows programs that will be airing at least an hour from now. Nothing live. If I go to the “heart” category I can’t scroll through the icons. I can scroll through the categories at the top left and right ( all, hd , favorites, etc) but not the channel icons underneath.

That's strange. What version of tvOS? Is the clock set correctly on both the dvr and client?

I deleted the app and reinstalled and now it’s working. Thanks for the quick response.
