Group Audio Settings Not Applying to Rally Bar Devices in Logitech Sync

I’m facing an issue with Logitech Sync (Enterprise plan, Sync Portal v2.3) where group audio settings (e.g., mic sensitivity) fail to apply to Rally Bar devices in a 10-room setup. Environment: Windows 11, Chrome 126, Sync App v2.1. Firmware: Rally Bar v1.9. Steps tried: re-pushed settings, rebooted devices, checked group assignments. Error: “Settings update failed.” Could this be a firmware or portal bug? Any debugging tips? Thanks for your help! 😊
