THis is a restriction from Facebook.
Facebook does not allow to impersonate other users. You can’t post comments on facebook on users behalf.
I can understand how that makes sense from FB’s standpoint.
Thank you for the prompt response …SNAP plugin working perfectly.

SNAP working great …WP posts got to FB perfectly ….and FB comments on the post are returned correctly to WP site.
However, if a comment on the existing post is made on WP site, it is not posted to FB. I looked around …guess this feature is not supported(?)
Great product…thank you for support.
Using SNAP V 3.5.3 on WP 4.4.3
