The Meta connection has expired or been invalidated (password change, app revoked, old session). Ads Editor can no longer act on Meta on behalf of the account.

How to fix it:

  1. In the side menu, open the Connect Meta page.
  2. Click the green Reconnect/Refresh button, sign in to Facebook, and accept all permissions.
  3. Go back and repeat the action that failed.

In public reports, the report owner must reconnect. After that, the link loads again on its own, without recreating anything.
