How to connect a new account in the FB Pages Feed app

You can connect new Facebook Pages from which the posts will be collected and connect social media accounts that those posts will be posted to. 

The Facebook Pages for posts collection can be connected in FB Pages Feed app -> Pages > New Page button > Connect Page.

The accounts can be connected in FB Pages Feed app > Pages > desired Page > New Account > Connect Account > Select the network to be connected. You can connect there even Facebook pages and groups. All of these are called Accounts.

Once an account is connected, it will be used to post Facebook Pages posts.
