Hmm, probably a dumb question but I can't find 3840x2160 as an option in GO 4 app. All I see is 2720x1530 30fps. Am I missing something?

You probably have set the live video feed to 1080p, then 4K is not available. Turn it down to 720p and you'll be fine

Thanks, figured it out going through the menus again. I wish hadn't upgraded the firmware, seems to drift in and out of atti mode indoors, before no problem.
