I have had a DJI mini 2 with the rc n1 remote and I just bought the DJI mini 3 and want to use the old remote I have tried everything and it still won’t pair

Hi there, please make sure the firmware of the remote controller is updated to the corresponding version. The latest firmware version is v04.16.0300. https://dl.djicdn.com/downloads/ ... elease_Notes_EN.pdf
You may also refer to the picture below to pair the remote controller and Mini 3 to see if it works.
