Hello all,
*** Please note: this replaces a thread I posted a few weeks back. I made the mistake of including a link to my Flickr site with drone images on. I hadn't remembered that this was against the rules, so the link was quite rightly...
I took a quick look at the manual for the controller, and you are correct, it doesn't look like they included the rotation lock button in settings. However, there is no doubt your screen rotated, so DJI didn't remove the rotation functionality...
