My Facebook Messenger makes me very confused when I'm using it. When my Account was logged in to Messenger, it displays an old version of the App when I already updated it. But, when other account was log in, it shows the newly updated version of the App. I've done alot to determine the possible solution of this but I didn't find some. Btw, I'm using Samsung Galaxy J1. I hope you can help me. Thank you for your answers.
