is the pro compatible with the DJI Mavic 2?

Not after my testing this past week. It is completely incompatible with the iPad mini 4 Mavic 2 Pro combination but I would recommend another app until this issue of Active Terrain Calculations is addressed it is a decent and most importantly RELIABLE software that does what you need it to do which is data collection.

We do the majority of our testing using the Mavic 2 Pro and there have been hundreds of flights posted using it just today so I am not thinking there is an issue with the latest version of the app. 

The iPad Mini is likely the limitation. We recommend using an iOS device with an A10 processor or better, especially if you will be doing CPU intensive tasks or really large missions. I just did the layout for your whole area on an A12 processor and it took 3.5 seconds. 

The area you are trying to map is 1.5 square miles and requires 25-ish batteries (likely more with the terrain changes). When you do the terrain plot calculation it is doing it for the WHOLE flight. With an older processor you should try to trim that down a bit and just cover the area you will be able to handle with the next 1-2 batteries, not all 25 or so.
