I am trying to set up a separate organization for each of my courses in GitHub Classroom. Even though I (and my school) have applied and been approved for GitHub Education I am only able to create organizations with public repos. I found a few other posts on this topic which give a link to this page - https://education.github.com/benefits - and say that you should just be able to click ‘upgrade’ next to the organization names. However, I get a page that that says I need to apply for benefits and submit either a photo of my staff ID or an employment verification letter. Haven’t I already done this? Do I have to apply again? Is there something I am missing?
