I recently sold a Mavic 2 Enterprise Dual with Smart Controller. I read a similer question/response from this time last year but my question is slightly different.
Before handing over the M2ED to the new owner I deleted all my logs, videos and photographs then logged out of my account. I deregistered the drone with Transport Canada. The buyer logged in and the M2ED seemed to work correctly. Can you confirm that there were no further actions required on my part and that all my data remains confidential?

Hello there Ralphhuttonthompson. Good day and thank you for reaching out. The new owner of the said DJI Drone can't get into your DJI account unless you give him your login information, or sell the DJI drone with your device included & still logged into your DJI account. To log new flight records the new owner would create their own DJI account & begin synching flights. Thank you.
