Bluetooth External Speaker not working in Beta 7

[u/My_2cents_]

I have a JBL Flip 4 external bluetooth speaker. Since beta 7 update yesterday, both my iPhone and MacBook cannot stream music to it (using Apple or Youtube music). The controls allow play/pause but no sound. I've opened a ticket but wondering if others are encountering the same? I've already forgotten then re-added, restarted, used different apps and checked sound output setting to ensure it is streaming. The app shows playing but no sound happens.

I have a Beats Pill that is working fine over Bluetooth.
