Hello I am at C4W3 assignment, i create the workspace, put it on Idle as instructed. then i execute the shell commands to copy the file. i launch as jupyter notebook and i only see the de-c4w3a1-studio-workspace.ipynb. There is no 4_W3_Assignment.ipynb. I tried deleting and recreating the workspace several times. I see the files is in the S3 bucket, but it doesn’t appear in the “pop-up window” as instructed.
