Absolute garbage app. Deactivated Facebook two years ago, have been using Messenger just fine. Reactivated my account for five minutes, and now suddenly EVERY SINGLE ONE of my Messenger contact is told I am unavailable, even though I can still message them. Zero ways to actually contact Facebook's actual tech teams, as everything is automated garbage with genuinely useless answers and advice. I have logged out and in, uninstalled and reinstalled, and it is still broken. Fix your garbage app.
