Currently SS does not work to notify PayPal of tracking info and ship status. I am told by SS that they are not integrated with the correct PayPal API to allow this to happen. This is a big disadvantage for PayPal users, causing us an extra step by having to manually update each individual order in PayPal with tracking information. The current integration between PayPal and SS is not complete. SS, please do what is needed to integrate fully with PayPal.
