I have been using my air 3 for the past two months for roof inspections. Today, after taking pictures I downloaded to them to my computer. When I went to take some more, Those photos mysteriously did not show up in the drive on my computer.

It is the Sandisc that I bought with the drone, it’s been working fine since new.

Could I have inadvertently triggered something on the controller screen?

I could not find them on the controller.

Hi there. Thank you for reaching out and we do apologize for the inconvenience. Please try to remove the SD card on the aircraft and insert it into your computer using a card reader then check if can find the said photos. You may also try to back up all the files on your SD card and please reformat it then try to have a test flight to see if the issue persists. Hope this helps.
