Roon stopped seeing Audio Zones/DAC after update to build 903

Support

I have exactly the same problem after Roon updated to build 903.

  • Same Mac as Core Machine and remote : iMac 27’’ mid 2011 Mac OS 10.13.6
  • Dac connected to core via USB : Schiit Modi 3+
  • Only local files

Is there a way to revert to build 898 ?
