When using dual remotes, our "master" controller will crash during flight, sometimes during recording and it happens MULTIPLE times.  The "slave" remote stays connected but gives us total loss of control of the flight path etc.  This can be very dangerous when out in the field with clients who have hired us to do a job.  

Has anyone experiened this???  Looking for thoughts on how to fix the app crashing during flight/recording.  All of our firmware is up to date..batteries and remotes included.  

PLEASE HELP!!

In our i2, DJI GO4 started shooting down midair since the last update...

Hi Bando
Your app would crash during flight， right？
Does it happens only when you using master-slave control？
Can you please tell me what·s the mobile device are you using？And app version？

Bando, could you happen to reply the questions provided by post 3#? we would like to help you, thanks.
