I've tried deleting and reinstalling. I have no notifications but the red "1" won't go away.
Hello mmj322,
Can you please provide more information about the red notification you are seeing and a screen shot if possible.
If it is a red '1' on the Notification 'bell' icon, you'll have to open notifications and look to see if there is one that hasn't been read/acknowledged. Scroll through the entire list or if there is a 'mark all as read' option select it.
