My drone is not working and DJI said to send it back for warranty repair. They sent me 3 emails telling me what to send back and how to send it, they also said I would receive an email within 34 hours with mailing label. After 24 hours went by I called DJI and the person that answered said mailing labels are sent between 24 and 48 hours after first set of emails. Now it is more than 48 hours with no mail in label.
