Hi Alex,
I'm desperated :S What you are trying to do is something it's already working, I know that.
The issue is from the "All courses" page --> https://academia.looksanddiy.com/course/
I've already tried to deactivate plugins and resave the permalinks but it does not fix anything. Could you please check further?
This is the video where you can see:
- It's working OK from My Courses page --> https://academia.looksanddiy.com/members/teststudent/course/
It's NOT working from All Courses page --> https://academia.looksanddiy.com/course/

Thanks for your support,
