Balena Sound BT not reconnecting/multi room not working

I’m trying to setup balena sound as a complete noob. I was able to flash the os to a disk drive, then was able to see the device and dashboard. From the start, airplay, spotify and multi room audio didn’t work, but Bluetooth did, which was good enough for my application. However, If I press “forget this device” from my phone’s bluetooth menu, I can no longer reconnect and have to flash the drive again.

Anyone know whats up?
