SO I am checking one of previous course. This course's first section was free.
But now I can not see the option to make the first section free.
here is the screenshot: http://prnt.sc/uwzt0n
Right now user can't access the first section. he has to pay to take the course.
here is the course link:https://krishipathshala.in/all-courses/
Well yes this setting is not added in the V4 right now . Yet to be implemented properly .
you can disable from backend lms-> all courses -> edit course
