Anyone else seeing this. Update went smoothly, rebooted everything, went in to Go4 app to verify all settings and now noticed the ability to record video at anything higher than 2K is gone...

go to the settings put in on manual then go back to auto your 4k will be back.

Thanks but unfortunately did not work. Reset camera settings and doesn't matter whether in auto or manual camera mode, can only go up to 2K , anything above is not listed.

Same here! Just did the update and I'm also stuck at 2.7k!? Camera reset and switching between manual and auto mode didn' work.

Worked for me, there are other threads about this, check em' out.

I have been answering this question several times a day!

The update defaults the cached video feed to HD. With HD feed you cannot record in 4K which has always been the case. Just need to change the cache feed back from HD to normal under the HD menu item in settings.

Thanks for tip, did not realize this before. Your solution is better than mine. I ended up doing Factory reset using DJI Assistant and 4k was back. When I looked into HD settings I noticed it had gone from HD to normal mode and I had always had set to normal previously. Evidently the firmware upgrade decided to set it to HD.
Anyway, I did not realize when this was set to HD that 4k resolutions became non-option but I do now. Thanks again!
