Paramount Plus Local Channel

I'm a little confused. I, too, have Paramount + as a streaming service but don't use it to access local TV. I think the problem is with Paramount misidentifying your location and giving you a major market feed instead of Columbia, which is a secondary market. (No insult intended.) I have a similar problem with PBS. I am midway between two major markets, and when I use their app to try and change my local station, I get a message that there is a problem with my choice of providers.

Are you using a streaming device, or are you using the software that is on your TV, e.g., Google TV. That might be something for you to try to see if Paramount + behaves differently when you change the way the signal is fed to your TV.
