the UK seller phoned me and said they only replace up to 2 weeks from purchase
and this is the reply I got from DJI.
Thank you for contacting DJI Technical Support.

Part 2----As per checking the information that you have provided, we would like to apologize since we can only process a replacement for you if it is still within
