Help Forum » Can't submit feedback to students!

When I was giving students feedback, I couldn't do it. I clicked the "send feedback" button and it was processing and wouldn't submit it! Would you please help me with that?

This is my exact problem. Can someone help? The program said the I reviewed it and the remarks are saved, but none of the students have received the emails. And they are not in their junk mail. GHow can I resend?
