Favorite lessons?

I can still mark any lesson as one of my favorites to come back to it later. Unfortunately, this isn't possible anymore, the page described in the documentation doesn't exist anymore : https://www.guitartricks.com/blog/how-to-use-lesson-favorites-and-lesson-history

It's not even a 404 error, it leads to the History page which lists all the lessons I watched and so is useless. Are favorite lessons a deprecated feature?

At the top of the GT page, near the right corner, click on Account.  A "Favorites" option should show up ready to be clicked.  That reveals a list of old Favorites.  Saving new Favorites may be another problem.

Thanks a lot!
