My flight mode switch button on the remote controller does not switch to the sport mode.
When the mode switch button is in the middle position the air craft is in Normal mode.
Even when I change the custom mode button (third switch) to Sport mode in the controller settings, the mode is normal mode.
Manual mode works fine when activated through the controller setting.

The button function properly in the simulator.

The same is happening with me. I didnt try it in flight since it happened. I fly a lot in sport mode and everithing was ok but today i saw this problem happening with the landed drone....
