Facebook/Instagram Connector Authorization Error
This article will assist you with the following error:
Authorization Error - Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.
Solution:
Manually disconnect and reconnect the affected Facebook Ads, Facebook Insights, or Instagram Insights data source(s) in your hub using the instructions at Disconnect and Reconnect a Source from Your Hub. This will not impact any existing reports.
Because Facebook Ads, Facebook Insights, and Instagram Insights all share the same underlying Facebook authentication, a session invalidation event (such as a password change) may affect any or all of these connector types. If you receive this error with more than one connector, disconnect and reconnect each affected data source.
