OV/Cardinal returns

Since the new procedure started a few months ago by scanning the QR code to enter the serial number for each item to be returned it’s been working & i haven’t had anything sent back. The last 2 weeks I don’t know if it’s a glitch or if they decided to stop doing it because i haven’t seen anything, but it’s not asking for the serial number to be entered. I bypassed last weeks & haven’t done this weeks because it’s the same drugs as last week. I just don’t want to do it & then get everything sent back because it didn’t have the right numbers. So has anyone else had this issue & what are you doing?
