Hi and welcome to the forum community @johnjeang! I’m not 100% sure on this but I think not all videos will have author’s notes. I wasn’t able to find a video with them. I checked out the link you provided and like you mentioned it did only have the three sections. If I can find an answer to this, will let you know here.
Hi @johnjeang! Sorry about the confusion here. We recently did a design change to our site, where we renamed a section called “Authors notes” to “Resources and updates”.
So whenever we say “Authors notes” in the video, that refers to the “Resources and updates” section. I hope that helps!
