A heads up. The latest firmware update (01.64.08.18) has made it so the controller won't import KML's. I get an Invalid KMZ error. A few other pilots have had this happen to them as well. Also, the altitude of Manned Aircraft ADS-B on my controller map is now wrong by a factor of 3. Rolling back the firmware made it possible to import KML's again but, did not fix the ADS-B altitudes. I saw someone mention that DJI is aware of the KML issue.
An aside: To roll back firmware. On the Main DJI Pilot 2 Screen, Long press in the top right corner where it has a green "Normal" status. You should then be able to choose what firmware for the drone or controller you want to roll back to.
