No, that's not the type of lag I'm talking about. What you describe is like the type of lag when switching zooms, but I'm talking about physical button presses that don't register at all. I think there are a couple issues at play. First, I think the controller doesn't queue commands, or at least doesn't do it very well. So if you click to stop recording video, and then click to switch to photos, the drone will not recognize the second click a lot of times up to a few seconds after the first click and the camera stops recording. Second, the buttons are sort of picky about what kind of presses they'll respond to. Sometimes I can press a button quickly and it's fine, but other times I have to be very deliberate and almost hold the button for a second to get it to respond. At least for me, this issue is primarily when switching from photo to video and vice versa using the physical shoulder buttons.
