Haven't used my drone in quite a while due to health setback but noticed there's a new controller firmware upgrade version v01.04.03.00 Can't find anything on it or what it upgrades or changes. Does it have any flaws or create problems after the upgrade and what does it change. Can someone who has upgraded inform me before I attempt the upgrade. My Phantom 4 Pro + is working fine at it's present configuration don't want to screw that up by upgrading to the newer version if it contains bugs. Anyone responding thank you.
