While reading a text message today, I received a notification from facebook. When I opened the notification, it opened facebook in split view rather than switching apps. I've been trying to find a way to do this since I got the phone back in December to no avail and cannot for the life of me figure out how it happened today. I've been searching the internet all day trying to see if there's away to do this but have turned up nothing. Does anyone know how to open a notification in multi window, and if there isn't a way, can anyone explain how this happened today. Thanks in advance.
