There’s an issue with the PLEX Roku app. I and others have discussed it in other threads (link below). Some attribute it to unsupported content, while others to networking issues. I can confirm based on deductive testing that the problem lies with the PLEX Roku app, itself.
In summary, the PLEX Roku app puts a severe strain on my server, resulting in buffering and failure, while the same server doesn’t break a sweat streaming the exact same content to an Android device.
