Photo Stream Not Working

I have downloaded the Photo Streams app to my television and uploaded the photos that I would like to have stream. But when I go to the screen saver on my television, I'm getting the same two beach and forest photos. I have completed all of the troubleshooting steps including checking for updates, and going to Settings > System > Power > System restart, etc. My photos are loaded in the app. They show up when I log into my account from a desktop, from my phone and my Roku Remote Control app. They are there. But they do not appear on the television screensaver. I have searched the discussion community and followed the troubleshooting steps as directed to no avail. Please advise.
