Ok then,how do you change the privacy settings? Say you have a restricted friend and you want to customise " whats on your mind" in others words not let them see your update!
Tap the three bars on the top left, scroll down to bottom tap settings and you should get to account, privacy settings. Think it's buried in there somewhere.
The Facebook app is sadly lacking in a lot of ways I haven't looked into that aspect of it though. It almost sounds like you have to go to the full site, make those changes and see if it sticks on the mobile version.
