I’ve just ugraded from MooWoodle 3.1.10 to 3.2.1 and the Moodle Linked Course drop down when creating or editing a product is not populated with the list of courses synced from Moodle. The list is empty. If I uninstall 3.2.1 and revert to 3.1.10 then all drop down IS correctly populated with all the courses.
As per our current flow, you need to first sync the courses and goto Courses tab (https://prnt.sc/L6krPPI3AJ3o) to see all the course and their assigned product.
Now if a course is already assigned to a product, you can’t reassign them again with a another product.
