My 'About" in the DJI Go4 App (V4.1.22) shows both the AC & RC Versions the same, that is V01.04.0200. I note that the Overview for Firmware update 2018.2.9 shows the Remote Controller Firmware as V01.0.0.0 as below:

Overview Date:2018.2.9 Aircraft Firmware: V01.04.0300 Remote Controller Firmware: v1.0.0.0 DJI GO 4 App iOS: v4.2.5 DJI GO 4 App Android: v4.2.5

Is this a typo?

Sorry for the misleading and thank you for your report. The firmware of the drone and RC should be shown in the same version. Now the release note has corrected. Thank you again.

This is not meant to be a reply but I can’t see how to post a question. I have just upgraded my Mavic 2 to the latest version using DJI Store assistant But it would not update the firmware in my remote controller. For some reason I couldn’t do the update with DJI go
