So I´m upgrading my P3 to the new 1.1.9 firmware right now and just realized that
the RC does not need upgrading from 1.1.8, the mail from DJI says so, ie it only affects
the aircraft and not the remote!
Yes after reading the release notes there is no need to update the controller. The app notification is a general notice and is not based on whether our not you have done the upgrade. Not sure why that is the case but never the less you should be fine as long as you have confirmed the craft has been updated.
