You should be able to dowgrade your firmware to previous version you had there, using DJI Assistant 2 software. If you do so, I am wondering if this SD card issue goes away?
I am tempted to update myself, I am still on old .0200 FW; someone commented earlier that this new version fixes this gimbal glitch issue, but reading that some folks are having issues connecting the drone to their computer and getting data off...
****UPDATE****
DJI are actually amazing.
They have issued a brand new replacement drone, free of charge.
Best company I have dealt with so far, honestly.
I have both the A3S and Mavic 4 Pro Creator edition. I'd definitely go for the A3S if youre on a <$2000 budget. The combo (plus an additional 2 batteries, 5 in all), ND Filters, a more powerful charger, backpack or other carrying case...
Same here. AIR 3s at first, then sold it for the M4P, and noticed it straight away soon as it start flying.
Don't get me wrong, the M4P has some amazing features, but the extra weight is definitely there, and felt when when flying in S mode.
