What is the delay on balena sound AirPlay?

Hello there, I'm curious about the status of the balena sound AirPlay feature. Can you tell me what's causing the delay and when can we expect it to be resolved? It's been quite a while since the announcement and we're all eager to get our hands on this feature. Is there any specific reason behind the holdup or is it just a matter of finalizing the technical aspects? Any insight you can provide would be greatly appreciated.
