Haunted Piano lesson not working

This is Nuno, Nicholas parent.
The coding lesson related to the haunted piano doesn’t seem to be working.
My son followed the instructions, we both looked at the tips and tried different approaches with different languages (block, python, etc).

Nothing seems to fix the problem.

Has anyone faced this issue or do you know how to resolve?


Your parent account has the solution for all the puzzles. For example this one required setting up the right notes for all the keys.
