Hi @laird_dave have an update from the developers. As mentioned, we are working on this issue.
It is related to the LE audio which is a next gen wireless Bluetooth audio standard designed for superior audio quality, ability to stream on multiple devices and battery efficient. The core reason is LE audio not working properly when access through the code in the phones.
For now, there are no ETAs. Will share the dates when I get some updates from the team.
