All the audit.feedback is a string in the AdManagementAPI [e.g. here](https://github.com/InteractiveAdvertisingBureau/AdManagementAPI/blob/master/Ad%20Management%20API%20v1.md#bidder-receives-a-webhook-call-from-exchange-) However, the audit.feedback is string array in AdCOM [url](https://github.com/InteractiveAdvertisingBureau/AdCOM/blob/main/AdCOM%20v1.0%20FINAL.md#object_audit) May I know which one is correct?
