Thanks for contacting support, I’d be happy to assist here. What exactly do you mean by Smart Graphics stopped working? Is the Explore menu failing to load or are the controls not appearing properly? I have a few other questions/suggestions:
Can I please ask you to reboot your Nucleus, your Core and any networking gear you have?
Are you using the newest build (build 7) from our Crestron Module Page?
Do the zones show up as expected in Roon Settings -> Extension or are they missing there as well? The zones should show up as follows:
If the zones are not showing up as above, then please perform a “recompile all” on your SIMPL program and then send it to the processor once more and verify if they show up then.
Please let me know if any of my above suggestions help here.
