Task 4 validation bug (Docker start/stop) when I run docker start web-server, the "successfully started" checkbox lights up. But as soon as I run docker stop web-server, the first checkbox unchecks, and only the "successfully stopped" one lights up. Since a container cannot be running and stopped at the same time, it is impossible to pass this task.

Thank you for reporting this issue. We identified and fixed the problem in the learning module that was preventing progression. Additionally, we’ve now unlocked all levels so users can freely explore and continue learning without restrictions. Please update the app to the latest version and let us know if you face any further issues.
