Hi Wenninger,
About the Phantom 4 Pro + V2 (P4P+ V2), as you can see on our supported drones webpage, it is not supported by Pix4Dcapture at the moment and it is not in the pipeline to support it.
it has been reported that the workaround that is valid to make work quite nicely P4P+ V1 is not working anymore with P4P+ V2.
We have not tested the compatibility of this drone with Pix4Dcapture and then every feedback/info from users is welcome.
Best,
