So, these are the rules.
So, these are the rules: On a Facebook page, if a personal profile makes a post either direct or from Postly, it will show the Page profile as the author. However, a Facebook Group is like a forum, so whoever makes (a personal profile or a Facebook Page) the post will show as the author - mind you that a Page is also an Admin to a Group and can be used in making a post, especially from the Facebook Business Manager. So, if a personal profile makes a post to a Facebook Group, will show as a personal profile, and if a Page makes a post, it will show as a Page. Now, on Postly and most other 3rd party Content Schedulers that connect via the official API, you connect your Facebook platform using your personal profile account - you have to be an admin. This means that all Page posts will appear with Page as the author and all Group Posts will appear as personal profile as the author Also, the API allows connection via your Facebook account (personal profile) and not as a Page - this way it can display ALL your Pages and Groups Allowing you to connect via a Page instead of a personal profile account would have solved this, however, it is not efficient because users with 100s of pages would need to connect 100s of times.
