If your groups and pages don't show up on in the facebook connections -
it's likely because it's a new page or a new group that has been created after the original pemissions were granted by the app.
these steps will resolve it for you .
and business integrations.
then log back into Social Post Magic
And click to add a new facebook connection -
And because the app has been removed it will prompt you to re-authorise your permissions
And all pages and groups will show up.
Apologies that this is a few steps but - it's a facebook thing not from our end.
