Facebook API does have a bug where it doesn't send us the webhook event "message_reads", which we use to display "seen" status on our inline stats feature. Inline stats for blocks and the Analyze Tab could be incorrect until they resolve the issue. You can follow the direct bug report here: https://developers.facebook.com/support/bugs/655968861668860/ - we will provide updates as soon as we hear from them.
