Weirdness started yesterday. the remote is sitting beside the drone.  I get the image transfer signal warning right away.  If I go into transmission options it's set to dual band auto channel mode.
if I manually change it to 2.4ghz,  it works fine.  if I change it to use  5.8ghz it will not connect at all. so every time I start the rc I need to manually change it to 2.4ghz. then all is well in my world.   its never done this until yesterday.
I refreshed both drone and rc using dji assistant with no change in behavior.

Just tried again and the 'Tranmission' windows shows nothing

Thanks for listening
Fred

remove the microsd from the drone and see if that helps. I've had similar trouble with some crap cards.

Thank you for your response. Kindly please test the unit outside with a strong GPS signal to see if the issue persists. Please record the screen if you still experience any errors outdoors so we can check. Thank you for your cooperation.

Same behavior. I only Brought it in to video it with better light. I have another rc. I’ll unbind both and bind the workable one and see.

I have two mini 3 pro's

drone (A)
drone (B)
RC (A)
RC(B)
drone A I sent to dji for care refresh
now I have
drone (B)
RC (B)
RC (A)
Drone (B) and RC (B) is having the transmission problem

bind  RC(A) to Drone (B)
to test if this works.
