1️⃣ Please visit Facebook and check the settings of the Facebook page you are displaying within Juicer, and see whether any country or age restrictions have been enabled. If so, turning those off should allow you to add the page to Juicer.
2️⃣ If that doesn't seem to be the problem, double check that the Facebook account connected on your Connected Social Accounts page is an admin for the Facebook page you're displaying. Having an admin connected there helps us better display posts in some cases.
You may also want to check whether the vanity URL for your Facebook page has changed. If so, you can delete the current page from your "Social Media Sources" panel of the Juicer dashboard, and add a new Facebook source with the correct vanity URL.
If you have any questions or need any help, please email us at firstname.lastname@example.org.
