DJI has begun contacting customers that have been backordered. Most customers that place their orders in the first few hours received it pretty much on time. Other than that almost all orders for the DJI Mavic Pro have been placed on backorder. DJI has now begun sending out updates like the email below!
Dear DJI Customer,
We are happy to inform you that your Mavic Pro order has been arranged and will be shipped on tomorrow. You will receive the tracking number of your order very soon. If you have any questions, please contact us at email@example.com. Thank you for choosing DJI.
