The major thing like best about this facebook page manger is the real time notification of messages , comments, views etc. Also , the facebook page manager make it very easy to move from one page to another if you are having more than one page and its less time consuming.
The only thing i dislike about Facebook pages manager is that you need to have more than one application to be able to effectively manage your Facebook account. Even though you have the Facebook manager , you will still need to install Facebook messenger, Facebook app, Facebook ad manager and this may require a large space for installation also it requires time to run all of this applications at once but it's still awesome to use facebook page manager because of it easy navigation from page to page.
The major problem i solved is been able to manage my page and solved the issue of not getting notifications of messages on real time.The Pages Manager makes managing business pages incredibly easy. you or your admins can easily choose from the list of Pages and begin uploading photos,making updates, and posting comments. The Facebook Pages Manager is also a useful tool because it allows you do a lot of things like:
It allows you to manage all Pages from the application, It gives you more space for making your posts, it easier to add text to the uploaded pictures.
It gives notification of new activity on each Page.
It gives you a detailed overview of insights and page statistics, including the total number of how many people the page has reached and how many people knows about the page. The trends graph
makes it easier to filter between different posts from different users.
