I was trying to find a way to ask help for Google Forms so I hope this is an acceptable place (official forums > no answer).
I am using Google Forms to create quizzes for my students but when I correct them I often find myself being unable to return them as, instead of the button "Release Score" I see "Updates made after release".
Does anybody know what this is about and how to work around this?
Google Help has no mention on this and my question on this topic has gone unanswered for more than a month.
Thank you
