I've been using Messenger with my Facebook Account deactivated for almost 4 years. After I reactivated it for an hour and deactivated it back, my friends on facebook is unable to send me a message on Messenger. They said I have this message on Messenger: "THIS PERSON IS UNAVAILABLE IN MESSENGER." Like what the hell? I haven't blocked anybody on Facebook! This is my second time experiencing this issue. FIX THIS!!!
