Live TV "Banner" load time - Roku

Why does it take forever for the “banner” the stuff at the top of the screen with the artwork of the show and details about the show that you’ve selected in the live tv guide?

On my roku 3 - wireless on 5G N network as well as my Roku tv this takes forever to load when I move from one channel to the next. Sometimes I don’t think it ever loads.

Live TV plays fine though
