(Firmware version 01.00.0900 and above, APP version 1.9.0 and above). c. The drone is now located in the European Economic Area (EEA). Once your Mavic 3 meets the above 3 conditions, a message will appear in your DJI Fly app to remind you to apply for the certificate. Alternatively, you can start the process manually via the Fly App. Fly App Home -> Profile -> Customer Service (top right icon) -> C1 Class Identification Label.
