Model reference is not updating in LayOut

I did some updating in SketchUp model but I do not see it in Layout even I did Update Model Reference. I am using SketchUp Pro 2021.

Share your LayOut file so we can see what you’ve got and how you’ve set things up. Most likely you’ve disconnect the viewports from the scenes in the SketchUp model.

Thank you Dave. I got it. It was a viewport problem.
