I pre-ordered my Inspire 2 the second day it was available through DJI (big mistake). I learned not to trust DJI because of the nightmares I and others have had with them over the years so I never updated the firmware on my I2. It's always worked great so my thinking is why risk it. My questions are will Cendence work with older firmware including the DJI app? Same thing with Crystal Sky. I'm (also) debating the idea of getting Crystal Sky due to all the reported problems. Thanks.
