 #### How do syncs differ between audiences with ID Sync and audiences without ID Sync? 
 
 Audiences without ID Sync aren't allowed to select any strategy, and by default will send all values of an identifier to the destination. Also, audiences without ID Sync don't send any custom identifiers that are present in your space.

 #### Can I edit config once the audience has synced? 
-Yes, you can edit configuration in the Destination **Settings** tab at any time. However, changes will only take place in subsequent audience syncs, or in new audiences connected to the destination.
