 ## Can I send audiences to multiple destination accounts?
 
 Yes, Engage supports the ability to send an audience or computed trait to two or more accounts of the same partner. The most common use case is multiple Facebook, or Adwords ad accounts.

+
+### Why am I getting alerts about an audience/computed trait sync failure, but when I look at the specific audience/computed trait it shows a successful sync?
+
+An audience/computed trait Run or a Sync may fail on its first attempt, but Engage will retry up to 5 times before considering it a hard failure and display on that audience/compute trait's Overview page. As long as the runs/syncs within the specific Audience's Overview page say they are successful, then these can be safely ignored.  The Audit Trail logic, however, is configured in the way that it simply notifies about every task failure, even if it then later succeeds.
