although it does sound strange and funny to me already having two Inspire 1 DJI is not able to distinguish the two units from eachother nor can you rename them. the logs I have (five of them) are all different and only the super busy tech guys in China may be able to correct that - they will never touch it -
just an info on my journey to clean up my flight logs which failed, because DJI is busy creating new units. I am not sure about the background but I am guessing it is a database filled with our stuff on some DJI servers. SQL or ORACLE maybe. in any case I am sure it would be possible to set an option for us to rename our craft since it is registered by the serial number automatically which should also be stored separately anyway in the database for the logs to show up also separately.
just my thoughts. if anyone knows better please let me know I am eager to know more about that theory. - nevertheless it is a pain in the rear to have a zillion flight logs and not be able to sort them or assign them to a unit.
cheers
