Multi room content issues

I have been using Kodi in a multi room setup with a shared MySQL database on multiple Windows PCs connected to TV’s for a while successfully and when I add a new movie the content(movie artwork etc) is available on all of my PCs. Now I have an android device on one of my TV’s and I can’t get the movie fan art to display without having to rescan the content and basically reset it up. I have copied the advanced settings.xml file to what appears to be the right directory but it still doesn’t work. Is there something I am doing wrong or is this a limitation between Android and Windows.
