The very first time you connect Facebook with TrueReview, you will see the list of pages you manage. Once you select the page to connect to, Facebook will save your settings.
If you have multiple businesses, you may want to connect a different Facebook page with the other location. In order to change Facebook's settings/pre-selection of the first page you connected to, you'll need to edit the previous settings when connecting every time after the first connection.
Luckily this is a super simple process.
When connecting your new Facebook page, make sure to click "Edit previous settings"
Now, select the new page you want to connect to and continue. Your previous connection to other locations will not change.
Important: Only select one location at a time.
