Player not playing when added to a Group Player

[VoltaicJ]

I have an iPad which is running the Home Assistant application and connected to a Bluetooth Speaker.
It shows up as a player on my Music Assistant home screen on other Home Assistant devices which allows me to play music to it. However if I add it to a Group Player and play something there is no sound even though it appears to be playing.
Also it does not show up in addons such as Music Assistant Juke Box.
I have enabled "Expose This Player to HomeAssistant"
Any thoughts?

If I understand correctly you are trying to add the THIS DEVICE player to a group? If so then that is not supported.

This whole functionality is being overhauled and will hopefully be pushed out in December.
