I set up an organisation, set up a classroom, set up a new assignment as an individual private assignment and added a starter repo. Copied the link and shared to students. When student attempts to click the accept assignment button an error appears:
Cannot make this private assignment, your limit of 0 repositories has been reached. You can request a larger plan for free at https://education.github.com/discount
What setting need to be checked / changed to make this work?
