Instance sourcePlayStatus "unavailable"

Moved from the wrong topic.

I'm trying to insert sourcePlayStatus into a variable, and it always shows as "unavailable." thought I was doing something wrong, but I checked the Music device created by the plugin and even there the sourcePlayStatus is "unavailable".

Is this a limitation of the newer versions of Apple Music? That's my source. And since AirFoil itself is playing, is there an option for Indigo to be able to notice Airfoil is playing instead of sourcePlayStatus?

Every other thing I try with the AirFoil plugin works (though I'm suspicious I'm having trouble adjusting volume of speakers.)
