You can now using the crystal sky monitor built in to the controller to download the amazon app and thru it purchase the Litchi app. I did this and they both download perfectly. problem is Litchi cannot override the DJI GO app built into the controller so Litchi cannot connect to the aircraft. I was told that these apps were just given approval by DJI recently so this may be a new issue to work thru on the built in crystal sky but seems to work well on the unattached crystal sky monitor. If anyone has any ideas I am willing to try em until I hear back from Litchi support or DJI. Thanks for your thoughts!
