As soon as you enter tracking data in your shop (manually, or automatically with various solutions such as Oberlo or Massfullfill), PayPal Tracking Autopilot recognizes this. The tracking data is then transferred fully automatically to paypal. This happens very fast. Usually it takes 1-2 minutes. If you enter a large amount of tracking data at the same time (> 1000), it can take up to several minutes.
During this time the autopilot is working and you can focus on important things.
