Question

If I apply or make changes to ID Sync or Trait Enrichment configuration, will the history of the audience, or the current audience members, be synced with the new settings?

Environment

Answer

No, changes to ID Sync or Trait Enrichment settings used on existing audience destinations or destination functions will not resync the entire audience, or its history. Only new data flowing into audiences follows the configuration. Hence, it is recommended to apply these settings to new audiences.

Configuration changes apply to new data flowing after about five minutes. Changes don’t apply to active or already running syncs.
