Why do calendar alerts sound when both notifications and sounds are set to vibrate only?
I have an iPhone 6 running iOS 9.3.2. I have always set my notifications and alerts for my calendar to vibrate. A week ago I randomly started receiving notifications and alerts as sounds. I have checked the notification settings under calendar and they are still set to vibrate. I have also checked the sound settings for the calendar and they are still set to vibrate. Does anyone know how to correct this problem? I like to see my alerts and notifications, but definitely do not want sound.
