Re-authenticating through Feedbird isn't always sufficient, and you'll need to disconnect from Facebook directly. This helps in totally resetting the connection.
If you're familiar with verifying permissions on Facebook, you'll have no trouble reconnecting Facebook and Feedbird.
Make sure you are logged in as the admin of the Page.
Select Settings & privacy > Settings from the small drop-down arrow at the upper right on your screen.
On the left-hand side menu, click Security and login, then Business integrations.
From the list of authenticated apps, find FeedHive.io, and click Remove.
Following this, the connection must be redone through app.feedbird.co.
FAQ
Can I schedule stories on Instagram?
Unfortunately, no. This is a limitation of Instagram's API, hence, no third-party tools can offer to schedule stories. We can schedule single images, carousels, videos, and reels with Feedbird.
Can I connect my personal Facebook page to Feedbird?
Unfortunately, this is not supported by Facebook's API.
