So I have a few questions. I don't have the serial number for the drone because I kind of took it off the label with the serial number plate thing when trying to repair it myself (I thought there might have been screws under it). I can't get it in the app either because I can't get the drone to bind with the controller. Anyways, do I need the serial number? The form I filled out with DJI never required it, but when I printed out the sheet to include with the drone, it said "serial number:" and then nothing. I'm not sure if that's necessary but plz lmk. Also, a shipping label wasn't included so where do I ship it? Would it be a better idea to go through a different repair service (DDS etc.) or is DJI the best way to go?
