I am running the latest version of Concerto VM in VirtualBox with a Raspberry Pi connected to a TV as my viewer. Everything is working great except for iframes. I am trying to view a Google Sheets file. I add the content and the preview in the dashboard looks great. I can even update the Sheets file with new info and the info updates in the preview. 

However, when I go to screens and Preview Screen and on the viewer, all I see is a black screen no matter what template I use. I did notice that when I reboot the viewer, I see the template for a few seconds and then it goes black. Other content works fine, just iframes. 

Anyone else have this issue?
