First, please be sure you're the Admin of any Facebook Pages you want to connect. Because of the way Facebook permissions work, we can only publish on your behalf to Pages that you are the Admin of. 

In addition to being Admin of the Page, Ripl needs permission from Facebook to manage your Pages. It's best to give Ripl permission to manage "All Pages" in Facebook. Otherwise new Pages created in Facebook and Pages not initially granted permissions will not be visible in Ripl. To correct this, go to your Facebook Settings > Business Integration. Click the box in Ripl and then select to "Remove." Once Ripl has been removed, completely close and re-open the Ripl app and try connecting your Pages again. Do you see the Page that wasn't showing up? If not, please reach out to our support team to continue troubleshooting.
