When looking at full screen map view, one of the small logos at the upper right "looks like an eraser," but I don't see anything happen when I press it. What does this do? Thanks!
If you have the "Show Flight Route" setting enabled in DJI GO (see the screenshot below), the flight path will be displayed on the map in DJI GO as you fly. It's sometimes helpful to see it when you want to trace the same path back to the home point. Clicking the eraser button will hide the last drawn flight path. If the "Show Flight Route" setting is disabled, nothing will happen when clicking the eraser button (since there is no flight path to erase).
