Latest DJI update 1.9.6 has done absolutely NOTHING to fix the RC Transmission Signal issues. Tested mine today exactly the same problem as a before i.e total loss of transmission at around 60 to 100 meters.
DJI WHAT ARE YOU DOUING ABOUT IT!
Has it ever occurred to you that yours may be a hardware fault? No software updates will ever fix that. It could even be something as simple as an antenna plug adrift within the drone.
What makes you so sure an s/w update will fix it?
