Google Chromecast 4K - No Guide?

Very different client guide experience on IOS vs Chromecast. The guide on IOS defaults to ALL Channels and actually attempts to show something, however the guide on the chromecast version of the app defaults to News category and then says there is nothing here.

How on earth do I map the channels to all these built in categories?
Why doesn't my chomecast cleint have an option for ALL Channels?

Make sure in settings that you have the All Channels option turned on. Somehow mine was turned off and I think one of the beta updates did that.

Settings -> General -> Live TV -> All Channels Collection = On

Thanks, that was the problem.
