We are using "Unit Locking" option to force users to complete previous units and quiz evalution before viewing the next units, But after update, all units are accessible !
All plugins are updated:
Please note that now we have provided this setting in course settings and it is now course specific and also added a fix for this in 2.0.6.2 .
Please check " Previous Units/Quiz must be Complete before next unit/quiz access " : YES
in course settings .
Just open the course edit page and save this setting : http://prntscr.com/ac79jx
