Hi Lee, Changyeol,
Thank you for reaching out to us on Microsoft Q&A forum.
The units before the exercise are informational, with no Tailwind Traders sample matching what is shown. You are expected to read and follow along. When you reach the exercise in Unit 11, you will be able to connect to a VM, download files from GitHub, extract them to the VM's disk, and complete the exercise instructions.
We tried from our end; it's working fine for us. Kindly refer the below screenshots. Please follow the lab instructions, whatever mentioned in the right side when you launched the Lab.
If you are still facing any issue, please let us know in the comments. We are glad to help you.
