I have a fairly new TCL Roku TV. Everything is fine except that it thinks that I'm in Iowa! I bought it at Best Buy in Southern Illinois and have it in Missouri. I've entered my zip code in the settings but, am constantly seeing ads from Big Bend, Iowa. I'm not interested in their stuff and would rather see my local St. Louis ads if I have to watch them at all.
