Thank you very much for trying to help me, sure that my doubts will have an easy solution.
I just started today with the apple courses that he offers us on his website, and when I start with the first class he tells me that I have to leave a few colors and I only get one, if so, he will select an option that I have already set it to continue.
I have it on and I do not see the supposed volas that appear in the example of the book.
I leave you some captures as an example.
Thank you very much for everything and excuse my ignorance.
