we have a Roku Express. There are two options that appear on my TV screen at the bottom of the screen Roku Channel and Roku for streaming as others as well. Usually when I click on the ROKU streaming it will then offer me many other type of viewing choices such as Netflix etc. One of those choices is Living Scriptures. I then would click on Living Scriptures and chose a movie. As of last Saturday when I click on ROKU to get choices like Netflix, Living Scriptures, Now when I click on Living Scriptures it will go to a colorful screen that is moving right to left as you look at the screen with ads of upcoming movies then I click on the back arrow on the remote to get to the movie choices and the screen goes black. Sometimes when I click on ROKU streaming the screen goes black. I checked all the wiring ec to make sure it was connected properly and it is. Sounds like a streaming issue to me.
