Facebook messenger isn't working. When I try to send a message it says....something went wrong please try again later
So most of the time the real cause of this error is that too many logged in sessions to Messenger are causing a conflict. To fix it you really need to go to your facebook app-> account settings -> security and login, then under Where You're Logged In choose Log Out Of All Sessions, then reload Messenger and you will be prompted to sign in again and the app should be able to retrieve your messages.
