Hi, thanks for the inquiry. I would like to ask if you manage to update the firmware of your aircraft and remote controller? You may encounter this warning if the remote and aircraft are not the same version of the firmware. For your reference, you may check our video tutorial on how you will update the firmware. In any case that you may need to use the DJI Assistant 2, you could check the link below as well. Please keep us posted on the latest progress. Thank you for continued support.
