All about Business Manager

What is an invitation to a Business Manager?
These are special links that you can use to join a Business Manager with administrator rights.
Why do I need invitations?
We use them as insurance. In case the main social account to which a Business Manager is attached gets banned, I could link another social account to a Business Manager and continue to run ads. 
In the case of the store, these are necessary to transfer the Business Manager to your social account.
So how do I access a Business Manager with a link?
1. Log in to your social account
2. Follow the link (example: https://fb.me/2r847LQKifGN2ek); enter your first and last name; enter your password from your Facebook social account.
3. Done, you got a Business Manager where you already do what you want.
