Ok guys while connecting my Mavic Air to fly I am getting a message on my phone that says (Firmware Update Needed) is this for my aircraft, controller, or Go 4 app?

It's not for the app. Can't say which the firmware is for otherwise. Need more a screen shot. Otherwise, why not just update?

It will not be the DJI Go 4 APP. Tap the Firmware Update Needed, you should be able to see more details of the firmware whether it is aircraft or the Remote Controller. Currrently, the latest firmware version of Aircraft is v01.00.0620, the latest firmware of Remote Controller is v01.00.0200.

Ok on my last flight yesterday the message didn't come up, seems that sometimes it does and other times it does not?
