Bought a Chromecast today and of course, Plex was the first app I wanted to try with it. I notice that the picture quality was kind of spotty, and the title/progress bar would slide up from the bottom of the screen regularly. I've since tried casting with my Netflix app and I haven't had any issues. I'm assuming at this point that this is something with Plex.
Any advice would be appreciated. Server is running from a local Mac Mini, casting from iPhone download speeds around 200Mbps. Happy to provide more info. Thanks
