Hi. I've read posts and the manual, about how to take bracketed photos. Unless I have totally misunderstood the directions, I am supposed to hold down on the shutter button and a box will pop up giving me choices on exposure and bracketing, etc. this doesn't happen on my version. I can hold the button down for 10 seconds and all that happens is it takes a photo when I eventually let up. So what am I doing wrong? I'm using the latest version of Go for my Phantom 3 Standard. Thanks in advance!
