In my account options, I can only add licenses for Pro or Plus. I called support and they said I could not add any Starter licenses but they didn't know why. The only option I was given was to create a new account with a new email address - I am not changing my email address so do not suggest that as a solution.
Why can't I add a Starter license to my account? Starter licenses are clearly advertised on your website but are unavailable to me. This seems like false advertising.
