Try to be patient, send it in under warranty, and let them send you a new one. Hopefully you will be back in the air in around 2 weeks. If you need it for commercial purposes, and will lose money if you are not flying, then you can pay for express, but then you will be using one of your Refeshes plus express. I would not trust DJI to refund you anything if you submit under a Refresh claim. If they do refund you, it might take weeks or months of chat, phone calls and emails to get your money back.
