In Facebook I want to publish and comment posts outside my business page (where I admin), but can’t do it. According to this description: https://www.facebook.com/help/465690686905994 In each post (outside the page) in the top right corner of the posting box should be an option for selection, where I can select my personal profile or my business page. But I don’t have this option. Since that I can’t publish and comments as my page anywhere in Facebook except this page.
How I can turn on this option? Maybe I should make something in the settings of this page or my personal profile?
