The possible solutions are:

  1. Refresh the page (F5).
  2. Restart step.
  3. Follow the note: “Note: Some browser extensions, such as ad-blockers and dark mode extensions can interfere with the tests. If you face issues, we recommend disabling extensions that modify the content or layout of pages, while taking the course.”
