P4, Shield K1 (with GPS), DJI Go v 2.9.1 (latest) At preflight all systems are go. My K1 shows the HP and the little blue dot (My K1 gps position). Question #1; Once flying I want to change the HP. I moved to another location 50m away. I switched switch 2 five times to update my HP. It did not work. How EXACTLY do I update the home point? I see nothing in the MC menu to do this. Question #2: How do I SWITCH my P4 to go to my RC location instead? Again I found nothing in the app for me to allow this. Please explain the steps to me. I have spent hours actual fly testing and also going through the app to find this. I would think this feature would be at least easy and quick to navigate to and preform. What am I missing????
