Can someone advise me on how Facebook messenger works please? I recently was added by my fwb to his Facebook. Sometimes his Facebook has a green dot next to the message circle on his profile page, yet if I go into messenger from Facebook he isn’t showing as online? Likewise his last seen is sometimes there (usually minutes or an hour ago) then an hour later it doesn’t say a last seen anymore.
Does this mean he is randomly changing his settings to appear offline or am I getting totally muddled?
