Can I add multiple accounts?
Yes you can add additional ad accounts at any time by selecting "Facebook Accounts" in the left-hand navigation menu.
On the Facebook Accounts Page press the "Add Facebook Ad Accounts" button at top. You should see all of the available ad accounts associated with your Facebook account on the next page.
Select which ad accounts you'd like to manage through Vincere by selecting the box at left beneath the "Import" column and pressing the button at bottom right "+Add Account".
