Yesterday the new DJI GO App 4 for Android dropped onto the Play Store. This is the App that people will need if they have purchased the Phantom 4 Pro ( and Pro+ ) or Inspire 2. It will also be needed for the Mavic and Phantom 4 going forwards.
So you can imagine how annoyed people who purchased the P4P are to hear an IOS App might take until mid december to be available in the App Store. DJI issues a statement regarding it today. http://www.dji.com/newsroom/news/phantom-4-pro-app-shipping-update
