I have tried searching the forums and reading the user manual and can't find an answer to this. It is my understanding that the P3P can be switched to shoot either 4k video or 2.7k. However, I cannot seem to get mine to switch. When I am in the DJI Go app, I go to menu, then click on video icon, and then to Video Size option. Once I am on that screen I see the multiple video size options so that should be where I need to be to switch the video size setting. However the app won't let me click on any of the video size options that are shown in the attached screen shot. I've tried it with the AC connected and not connected and either way I can see the size options but it won't let me select any of them at all. Any insights on how to switch to the other video size settings would be appreciated.
