I have MS Surface Pro. You all are bragging about "New! Improved! You can now change color & look of tiles with 8.1!" It was a slow-go, but I downloaded and installed 8.1 yesterday. Still no go. Here, for instance, is what I want to do: I have a separate, branched off from "Sports" feed tile for Oklahoma Sooners, which you have arbitrarily created as blue. My main "news" feed tile you have arbitrarily made red. I would like to make the Sooner tile red. How?
