Buggy, coming up as unavailable on messenger to some people. So ever since the latest update , for some of my friends, they think I've deleted messenger, for others they think I've blocked them, and others can freely message. If I log in through a laptop on the website it says my messenger doesn't exist. But if I open a desktop site on a tablet or my phone then it opens normally, could this be a cyber attack by the Russians, or could it simply be the developers of the app, who knows.
