Swamp;
In response to your querry on Albert's page regarding Jriver remove app on iPad and Windows based computer, that's what I am using, and it works fine.
I have upgraded to Jriver 21, but have not yet upgraded my iPad to OS9...waiting for a bit more stability and to download the remote patch fix for the app on my iPad. I love the ability to control my music library from my sweet spot chair on my iPad, and use my Windows based PC, using Windows 10, and JRiver 21. My digital sounds pretty good at time. Hope this helps you.
