Alexa does’t send music to Windows Plex Media Players

When asked, Alexa says it is sending music to the requested Player, but no music plays. This is the case on two PC’s, one running Windows 7, the other Windows 10. Oddly, requesting Alexa to send video to the PC players works, as does sending video AND music to the Plex Web App on both machines. I get the impression searching this forum that the desktop players are now being demoted in favor of the web GUI. Given that Alex integration is a relatively new feature, am I right to assume that the desktop player is not yet fully compatible with Alexa and will become so in a future update?
