This worked!!!
I thought it might be helpful to share that the visual editor was a bit funny as I was following along with the steps… When I got to the step from min 5:48 in the video, my carousel disappeared in the visual editor. I stopped and started over several times with the same result and finally decided to just continue following along with the rest of the video… When I went to “View current draft” I could see that the carousel was actually there and looked as expected (yay!) but the visual editor looked like the photo below. After going OUT of the page I was working on and re-entering it, now the carousel is there so that I am able to edit the Product Box further. I’m not sure if the carousel was not rendering due to me working from my 13" laptop and the even smaller workspace of the visual editor but hope that perhaps this info might help someone in the future.
