if I want to revert to a lesson
Thanks for reaching out!
At this point we don’t have a way to achieve that inside the platform.
However, you can create bookmarks on your browser. Here is a detailed guide on that: https://support.google.com/chrome/answer/188842?co=GENIE.Platform%3DDesktop&hl=en
What I usually do is to create folders and subfolders with my desired bookmarks.
For instance, you can have a folder: 365 Data Science, which has a subfolder for each course.
Hope this helps!
