I went to onCampus > Group Finder, and selected one of my athletic teams. Then I went to the Schedule tab > Settings, and set Games and Practices to "Send Notification" > Yes > Save, but when I go back in, it's still set to No.
The publish notification goes out to users who have subscribed to the "Game Schedule Published" or "Practice Schedule Published" notifications found in the user's Settings > Notifications.
It is a one time deal! Once the school publishes the schedule and the notification has gone out - that is it. We wouldn't want to send people extra notifications if it was toggled on and off again - so in a situation where this was set to Yes and saved multiple times, the notification will still only go out once.
