Facebook is at it Again!
Facebook has recently removed the ability to log in and use Facebook as your Page from your settings.
You can still do the things that were available when using Facebook as your Page, but those features have moved.
You can choose to like, comment or share as a Page you manage from the dropdown menu on every post. You can also visit Pages Feed on the left side of your Page to see and interact with posts from Pages you’ve liked as your Page.
