Xfinity Stream app not showing LiveTV channels, only TV GO channels

There is a post here in the forum which I copied my Subject line from.  I have almost an identical issue.  On my android phone the xfinity stream app shows my local channels just fine.  I van watch Chicago CBS channel 2, NBC channel 5, ABC channel 7, WGN channel 9.  The xfinity app on my 2025 LG TV only shows a few channels and NONE of my local channels.  CBS, NBC, ABC, WGN etc. Please help
