Using the Shield 2019 remote to scroll on the guide.
Repro: if there's a long show like right now "Live Coverage: Winter Storm Isaiah" on the weather channel, when I press right to scroll later in the day the guide does not move right until I scroll up or down to another channel with shorter programs.
Not a huge deal but I've run into it a few times now and at first I thought the guide was broken until I realized I was stuck on a long program that was preventing me from scrolling to a later time.
I can screenshot it or post a video if that'd be helpful.
Doing the same thing on "The Dark Knight Rises" on TNT.
