EQUIPMENT SETUP:  Dual operator scenario-  1x RONIN 4D, 1x A Monitor w/Joystick Handle & Focus handle, 1x B Monitor w/3 Channel FF
when set to manual Focus mode everything works, when you switch to AMF focus does not work unless I remove the focus handle from Monitor A -  i think it should just disable the focus handle instead of having to remove it

PS - I would like to see the Multi focus points set by the 3 Channel FF while in mirror mode if possible

Keep up the amazing work Team DJI

Hi there, regarding the situation description, we would like to know and collect more relevant information with you to further confirm. Looking forward to your reply!

1. Please provide us the videos of the operation process.
2. Please confirm the firmware version of the monitors and DJI Ronin 4D
3.  May I know if it is still the same, after restoring the monitor to factory settings?

I had the same issue.  I reset the camera back to factory settings and everything started working properly again.
