Residential stop, signature required. No one home and was sheeted as not in 1. 3 hours later, drove by the house again while doing pick-ups. Made another attempt, again no one home, scanned package again and asked for late air reason when I hit stop completed. In the past, as long as an attempt was made before the commit time, you could make another attempt after the commit time without showing a late air. Anyone have any idea why it showed as a late air?
