I'm having a problem with the new Mavic Pro app. A few months ago I dropped my phone and broke it. It was replaced with the same make and model LG V20. My old phone had apparently an old app. DGI go 4 and it worked great on my other lg v20. I could see from my camera in my display on my phone take pictures and watch the scenery below from my camera on my drone. The altitude worked everything worked fine. I got the new phone and I've downloaded the app but it won't work with my replacement phone.I called DJI support they say they've upgraded the app and it does not include the LG V 20 phone. So does that mean they can update their app and exclude you because you have a certain phone seems like they should include all phones. Does that mean you're supposed to go out and buy a new phone every time they update their app I don't think so. Does anybody know how I can get a copy of the old app or what I can do to make it work with my phone. I'm hoping I posted this in the right place if not I do apologize, any help would be appreciated.
