I used QR codes for shipping labels many times however, today I run into a small problem. I created the QR code as before and then walked to the Post Office and tried to ship my item. (About 15-20 minutes from creation to arrival at PO) The QR code was not in their (Post Office) system yet, so I walked back home. I'm going to wait about 30 to 45 minutes and walk back up and try again. Has anyone else dealt with this delay, and how long did you have to wait before the QR code was received at the Post Office?
