I have a Universal Media Play defined with 13 children.
If I manually initiate playback on i.e. three of them - playing from three different sources;
No1 Plays from Spotify
No2 Plays from TuneIn
No3 Plays an MP3 track from a locally stored album
When I use the developer page to follow the state of this Universal Media Player, I can see each child and its states as I initiate playback, but the state only shows the info for one player (no matter how many are actually playing), and it only shows the one with the most recent state change.
Is there a way to get a named list of all playing children?
