I have an icon that has never appeared on the top left of my screen before. Typically when you receive notifications, an icon pops up in this location. You swipe down and it tells you what it is. I have never seen this one before. It is a lower case i with a circle around it and a line drawn through it. Can anyone help me with this or has anyone seen this before? When I swipe down it does not show me anything under Notifications.
