Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.
Our software integrate with Facebook Pages, and for the past month we have multiple users experiencing an issue with connecting Facebook Pages accounts to our software. It would appear the user's page token is being instantly invalidated for some reason, even though there have been no password changes on the user end.
This is the API response we get when making the call:
{"error":{"message":"Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.","type":"OAuthException","code":190,"error_subcode":460,"fbtrace_id":"AJt2zBIQh5IH7NqOuHzzSXZ"}}
What could be the reason for this error that is appearing for multiple accounts?
