When page administrators use Facebook they will now receive a pop-up asking them to “change attribution settings”. This relates to how they post: either as themselves or as the business page they are responsible for administrating.
This includes when they post on their own page or pages, on other pages or when they comment on posts of other users or page posts. When they do so the following message will now appear:
“Choose whether to like and comment as yourself or as one of the pages you manage. Post attribution settings.”
Underneath that is ‘Post Attribution Settings’ with an OK button next to it. Select that in order to manage how you post.
