I’ve owned drones since 2016 and yes I fly them, in that I normally rarely use the various quickshot offers or even RTH. No, I’ve never ever used waypoints so wouldn’t be aware of problems with them.
Maybe you didn't get the details right?
DJI has had 1" sensors in drones since 2016 and the Mavic 2 pro had one in 2018.
The Mavic 3 and Mavic 4 have had 4/3 sensors for a couple of years now .. that's almost twice the size of the 1 inch sensor...
That's not always true. The NDAs that I have signed have not prevented me from saying that I am under an NDA. Letting someone see hardware covered by that NDA would be a violation of that NDA.
And the US is probably the last place a pre-release...
