The documentation provided:

Is painfully misguiding. Following the steps for Kodi myServer App Configuration and State Variable Configuration and then Play Movie leads to utter frustration as it doesn't work and leads in circles.
However following the Kodi myServer App Configuration and then completely ignoring the State Variable configuration and Play a Movie section and load the provided kodi.html in the Modern UI template and that will play a movie and provide basic controls.
How? I dunno yet. As the app page is referencing the player id directly and the state variable for zones and movie aren't in play.
I'm thinking no documentation has been updated and there's some mix up between the previous Kodi "Driver" and the Kodi "App" and they are both listed and neither are documented?
