The 3D Cursor can still be seen here in the modeling tab However, 2D Animation Tab, there is no 3D Cursor. How do I get the 3D Cursor to appear back in the view?
You can change the display settings (3D cursor, grid, main axis lines etc.) in the Overlays menu on the top-right corner of the viewport. Each tab has separate display settings, so that 2D Animation tab happens to hide the 3D cursor while the other tab happens to show it.
