Xfinity Stream App on Fire TV does not show local channels

Hi,

I recently purchased a new Fire TV and downloaded the Xfinity Stream app. It is being used on out-of-home WiFi, and does not show ABC or NBC on the TV Go section. I have a second Fire TV, also on out-of-home WiFi, and the Xfinity Stream app has always had ABC and NBC on the TV Go section. It also works on my iPhone Xfinity Stream app, so it is clearly not a location, WiFi, or operating system issue. The ABC and NBC apps on the TV work and allow me to watch those channels when logging into my Xfinity account, but I shouldn't need to use 3 apps to watch TV. I have tried deleting both the NBC and ABC apps, as well as uninstalling and reinstalling the Xfinity Stream app.
