If you did not receive an update for a particular point, it could mean that the Event Organizer did not enable updates for that point, or your bib was not read at that point.
As of July 2018, Facebook no longer allows 3rd-Parties to auto-post on users' behalf. As such, we will no longer be able to offer automatic posting of your results on Facebook. Even if you signed up for Facebook updates for your race before the change went into effect, you will not receive updates on Facebook. For more on this change, this article from Business Insider offers some explanation of the change.
If you signed up for Athlete Updates for your race, but did not receive any updates at all, please contact the Event Organizer using the contact information on the Event's Web Page.
