My revit 2016 renderings have stopped coming through to the cloud. I have never had an issue with this in the past, when I set up a rendering in the cloud in revit, it has always started rendering right away or showed a loading symbol in my rendering gallery and said it was in line to be rendered. Currently nothing has come through and I have sent 4 or 5 views but nothing is showing up. I don't think I have changed any part of my process. I hit the "render in cloud" button when I am on the view, and set my settings to standard or final quality and medium or large size png file. Also it generally brings up a warning box about missing materials and it hasn't been doing that so it seems like its not fully sending them to the cloud. Any ideas as to why it has stopped working?
