Why does my Facebook Page keep disconnecting?

The single most common cause: someone else using the same Facebook login reconnected and didn't include your Page. Meta treats every reconnect as a full permission reset — whichever Pages the last person granted are the only Pages that stay connected. The reset is global to that Facebook account: it affects every PostFast workspace connected through the same login, not just the workspace where the reconnect happened.

Fix it in two minutes

1. Open Accounts from the sidebar.
2. Click Add Social Account and pick Facebook. If Facebook is already connected for this workspace, the same action triggers a reconnect — there's no separate "Reconnect" button.
3. On Meta's consent screen, open Edit access and choose Select all current and future Pages.
4. Save and try scheduling again.

Prevent it happening again

• On Meta's permissions screen, always pick Select all current and future Pages.
• If multiple teammates or agencies share one Facebook login, agree on the rule: whoever reconnects picks the "all current and future" option — no exceptions.
• Separate Facebook logins per brand/workspace where possible. If Brand A and Brand B use two different Facebook accounts, their Pages can't knock each other out.
