I'm having an issue where Marketo forces me to re-authorize Launchpoint add on when I try to send a smartlist to Facebook. I've re-authorized over and over, removed and re-added Launchpoint custom audience add-on, and nothing seems to work. Any ideas?
I got an answer:
If this is a newer implementation (it is), please ensure that the terms of service have already been accepted here: https://www.facebook.com/ads/manage/customaudiences/tos.php . We find that this is key in common authorization errors.
