I've sent a couple of messages to people (they are not FB 'friends' but long-lost former colleagues.) I've had no reply which is either because they just want to ignore me (hahaha) OR they aren't picking up the messages.
I'm not a huge user of FB and not au fait with all the settings.
Do they have to 'accept' messenger to see my messages?
Will they not automatically get a notification there is a message?
(I've switched off my own notifications as I belong to a work group with 4K users and it gets crazy!)
Could their replies be hidden so I'm missing them? (I've looked under All Messages on my account.)
