Let devices play to the speaker over Bluetooth directly instead of only through certain apps. E.g. Let my computer see the device and install it as a Bluetooth speaker. Alternatively, provide an app that will play anything playing on the computer through the speakers. The issue I am running into is that the Sonos Desktop Application crashes when I try to view or search my uploaded to the app music, but if I could just use my media player (MediaMonkey, or even iTunes), then I could use my already existing playlists and music library.
