Today I have updated the firmware on my 4 month old P3A but had to hold the SD card in the gimble slot for the whole duration of the update as it refuses to latch just keeps springing out when pushed firmly home. I suspect this is a problem that DJI have prior knowledge of as there was a bad batch at some time. Has anyone heard of this before, is there an easy fix or is it a return to DJI? I am in the UK the supplier has ceased trading so if a return is required I think it may need to go to DJI in Germany is this correct? Thanks .
