Lately when making/downloaded shipping labels, we've had to have the labels sent a few times for all of them to come through. For example, a merch store will have 16 orders that are shipping, but on the first email only the first 5 labels will come through, then maybe the first 10 on the second, and finally all of them once we've done it a third time. I don't know if something changed in the system but it might be worth looking at. Thanks!
