Pix4D does not connect to Phantom 4 pro+2.0

I can connect Pix4Dcapture to MAVIC AIR 2 (although can’t actually fly the mission), but i just can’t connect the APP to Phantom 4 pro+ 2.0. I tried to install ctrl+DJI and Pix4D on the controller tab and on my phone, neither one works. Does anyone have a clue? Very much appreciated!
