I'm having this issue where my facebook app informs me of a notification so I go to check it. And then the notification in the top bar disappears. Sounds normal right? But then, normally less than 5 minutes after I look at the notification, it pops up again. There isn't any new information, but it alerts me to the same notification 3 - 5 in a span of 15 minutes. Is there a way to change this?
