I used my MAVIC AIR with firmw. 0300 perfectly.
After that I upgraded to the firmw. 0400, all possible problems started to appear (drift, lag preview img, loss of video signal, etc).

I thought the DJI was going to solve quickly but I see that after 15 days, nothing was done.
To make matters worse, DJI does not enable firmw rollback by the DJI ASSIST application.
I know there are programs that do this rollback for the 0300 firmw.


My question is simple: Has anyone tried?

I have also experienced a frozen video signal the last 2X that I have flown my MA with a "Weak Video Signal" message following the last 2 firmware upgrades.  I am also getting EM interference messages over a field with little to know apparent metal other than a few signposts.
