In several different Google AdWords accounts we import conversions from Google Analytics (GA). Today (January 12th) in the AdWords accounts the last Conversions show up from January 6th. After that no conversions show up. Before Jan 6th a delay of 2 days was normal. Since it is not only in one account but in several accounts it seems unlikely that a change made by us triggered this.
What could be the cause? The conversions in GA show up in the same rates as before: No change in traffic or conversions.
