I've updated my firmware but the Go app is still throwing a warning that the 'aircraft' firmware needs updating.  I've verified in the DJI assistant app that it has the correct latest firmware.  Any ideas from the forum on why I'm seeing this?

Would you please try to restart all devices, or delete the APP, then re-install it?
If still the same case, please post a screenshot for the version on "About" page, and help clarify what mobile device you are using, thanks.
