Change in AGO World Imagery June 6 - June 27, 2018?

We are currently working on a centerline clean up project and using the World Imagery in ArcMap via service to update the spatial accuracy of the roads. Last week the service was updated (June 27th) and we noticed in some places the imagery had shifted up to 50 feet. After hours of investigating if something was wrong with our data, we pulled in the WayBack aerial from June 6 and the roads lined up to the aerial again. 


What caused this shift in the accuracy of the World Imagery? It wasn't uniform across the area we are working in (Eastern California.) We haven't seen any reference to this from Esri. Attached are before (June 6) and after (June 27) screenshots showing the shift in the aerial. 


Any insight or discussion is much appreciated.
