The reason/notes for a mass cancel should show up at the top of the email for users to see right away. Currently it shows all the way at the bottom and most are looking for the reason at the top of the email.
This would also be helpful when you are declining and an event as well. There are always questions from users as to why something is declined. But its because the notes/reason is given at the bottom of the email.
You won't be notified about changes to this idea.
