Just an FYI for you Playstation Vue and Roku users or potential users. We recently subscribed to the Vue service on my Roku 3. While they have ABC On Demand, strangely, not all of the ABC shows are on there. My wife wanted to watch The Bachelorette which is nowhere on Vue.
Also, I recently cancelled all of my Cox cable service except internet. By doing so, my "Watch ABC" app on Roku had much less content and couldn't watch the newest episodes. Well, I did some research and found that you can log in to "Playstation Vue" as a "Provider" using your Vue credentials. All of the content came back and the wife was happy.
Sorry if this is old news just thought I would share my experience.
