Now that I have the 4, I will be selling my mini 3 pro.  For those that have sold their mini 3 pro, do you have any tips on how to go about it?  For example I'm assuming you will have to deactivate it somehow from your account, factory reset to remove your data etc.

Hi there. Thank you for reaching out. If you are planning to sell this drone of yours, it is recommended that you remove the bound account and let the new user bind his APP account. To unbind the unit to the account, you may go to this path; DJI Fly app> Profile>Device Management>Account and Device>Remove the device from the account. Also, if you included the DJI RC, you may also reset the RC. To reset go to, DJI RC: Enter Settings>System>Reset options>Erase all data(factory reset). Should you have other inquiries, please don't hesitate to reach us. Thank you.

Hi, If I have Value Added Service still active/valid, do I need to unbind it also?
As in, I want to transfer the refresh service to new owner.
