I had the same issue before I reinstalled DuOS. But after I did it gave me a landscape app. There's also an orientation circle icon in the upper left corner you can try. I'm not really sure which fixed it though. I also accidentally installed the Amazon TiVo app at first and it didn't work right. So I uninstalled the Amazon app and then did the Google Play version and it worked well except for the streaming issues I'm still dealing with. It's almost 4:30am.....go to bed young man!
