I have three models I’ve created that I can see as 3 workspace files. As I was working on one of them, I went to the “Workspace” page and when I went back in the file is blank. There isn’t even any grid showing up. This is common to all 3 models now. They are there in the workspace page but don’t show up to try and work on again. I’ve tried zooming in to see if the grid appears at some point, but it doesn’t.
