Terrible I wish I could get my money back!!!!

Where are any instructions to use this app I have no idea how to make a flight plan actually execute on X-plane.... I hit execute on the app and nothing happens in X-plane
Note: I have the proper plugin running on my Mac and the map and plan works you can see that the heading is correct but yet the FMC on the app does NOT do anything to the FMC on the plane.
