I just finished posting a really, really long topic on how I fixed a problem I had after getting my replacement Drone. You will soon be getting your New Drone from DJI, but your Phone’s or Tablet’s Network Connection will still be “wedded” to your old, returned Drone. This has nothing to do with the Fly App or the software, it only has to deal with the WiFi of your phone/tablet. If you have problems performing a Quick Transfer with your New Drone, this is how I fixed it.
