Constantly says you have a notification, with the little "1" next to the class dojo icon on your home screen. When you open the app, there is nothing telling you that you have anything new, and there's no new messages, nothing under "Alerts" either. There are also no settings to control how your notification work. There no "settings" in the app whatsoever. Very bare ones. So, you're just constantly opening the app seeing if you actually have a message or something. Super annoying.
