If you have a Facebook Business Page, you may have noticed some recent changes to the page management for posting. Remember the cumbersome 'switch to business page' route you had to take so you could communicate as your business?
Well, you no longer 'log-in' as a Page to post as your business or access and interact with other Business Pages; you stay logged in as yourself. (See red circle on top of diagram below)
In the text box on your Business Page the status option defaults to your page, you can switch it to post as yourself or another page you manage by clicking the drop-down arrow. (See red circle on right of diagram below)
You still have the capability to post and engage as your business with other Business Pages your Page has 'liked', however, you now access your Page's News Feed directly from the left panel of your Business Page by clicking 'See Pages Feed'. (See red arrow on left of diagram below)
