Excellent app!

Just tried this for the first time today to watch a video from the jw.org website. We cast it from an iPad to the tv seamlessly. No pop-up ads, no glitches. Just remember to disconnect this app to go back to your other Roku options.
Open the app, locate your video using Google, click on the video selected, then look all the way at the bottom of your iPad screen. Click on the cast link, and enjoy.
