Hello, I've been messing with this for a long time . And all I can say is this. Set your zip code to the broadcast towers your antenna is pointing to or at. Or the towns zip code.
After doing this you may, or I should say, Do A Restart, after changing zip code settings. And any major settings change
And that seems to work for me. If I set it to my own. It shows no information available. If I disconnect the internet. And restart, all the information populates.
I think it has something to do with the internet provider,and Roku tv.,, although I've never had this problem before with same internet provider. But like so many others, it's still not fixed
Even after all the recent updates and patches.
I still must use improper zip code to see my channel guide information correctly.
Please correct me if I'm wrong. I'm just living with it so long it's not much of a bother anymore. Now that I know this Work Around!...
I hope this works for all
