I rcvd notice from Roku that I need to upgrade from my Roku 2 to a new Roku unit & I accepted an offer for 50% off a new Roku Express. Using Play on as I did previously, casting videos from my computer to my Roku player, the video may start then crash & I r'cve a message to restart Play On again. I can never get more than a few seconds of play, if any at all. I decided to keep my old Roku 2 for as long as it works & I hooked it to my kitchen TV which WILL play cast videos. I deleted & relaunched Play On to no avail. Checked for updates, etc. Nothing. Thanks, Lee
