How do I know if someone left a comment?
The New Comments button is a the top of the Home screen. When you have unheard/unviewed comments, you'll see a red notification on that button indicating how many new comments you have. You'll also see the red notification next to the Home button.
Tap the New Comments button to see a list of all your new comments.
To quickly view or listen to a comment, tap once on the name of the person who left the comment, and then tap on the play button next to that person's name. This will play just that comment.
To view or listen to the comment from the VoiceThread itself, tap the play button at the top of a list of comments, next to the title of the VoiceThread. This opens the VoiceThread so you can view all comments and slides in it.
