First, please be sure you are the Admin of any Facebook Pages you want to connect. Because of how Facebook permissions work, we can only publish on your behalf to Pages that you are the Admin of.
Ripl needs permission from Facebook to manage your Pages. To correct this, please follow the instructions below.
Once you have completed the steps above on either your mobile app or on your computer, return to Ripl and tap the My posts tab, then select Brand settings. You can then tap Connect next to your Facebook Page or Group. Do you now see the option to select your missing Page? If not, please reach out to our support team at firstname.lastname@example.org, and we'll continue troubleshooting.
