Hi, I bought dronelink just this week. Today I used it with my Mavic Pro and it worked great.
I also want to use it on my Phantom 4 Pro +, but the app needs Google Play Services and that one keeps crashing.. :-(
I think it's very nice to plan your flights ahead, including taking video's at the right moment, etc.. So I hope to exchange these flightplans between my 2 drones.
