Some of my friends chats say they are unavailable on messenger, as if they have left messenger or deactivated their account...and they haven't. Also, some of my friends say that my chat says I am unavailable on messenger and they are unable to message me, when I am still using messenger. My app is up to date and I have not deactivated my account or blocked those people. Please fix this issue. I have submitted a report....waiting for it to be resolved.
