DJI Mavic 2 Pro controller and Pix4D capture

I recently attended a Pix4D class in order to perform crash scene mapping. My issue is that I was able to get Pix4D capture on my Mavic 2 Pro smart controller and the DJI+CTRL.atk app, however, I am unable to get the smart controller to communicate with the Drone. The suggestions I have received thus far point me in the direction of buying an old controller or using an Ipad to control the drone. I don’t see the purpose of having a smart controller that I can’t even use to do mapping. Any other suggestions would be very much appreciated!
