I'm not sure what it looks like on DJI GO 4. Below are two screenshots showing the new position indicator in DJI Fly. The horizontal bars in the radar view show the attitude of the AC. The map view can show course up or north up.In Go the AC is at the perimeter which i feel is more useful (larger too) but in Fly the AC is at the center. Thats fine for orienting the AC to point back to you but not so much you facing it when you want to maximize signal. Have you found a way to switch positions between AC, HP and RC on the "radar" in the Fly app so that it shows like in Go?
The blue dot with small arrow shows the RC and the direction the antenna is facing. The plus and minus button in the upper right of map view will slightly zoom the view in or out. The map view will also go full screen.
Hope that makes things clearer.
