I formatted the ss card on my PC with exFAT but the camera wouldn't recognize it and I formatted it on the osmo action 3.  When it was done successfully formatting it then also said failed after confirming the successful format.  But the SD card still worked anyways inside the camera.  I took the SD card out of the camera and put it in my PC and it said the SD card would need to be formatted (I do this with numerous other cameras and SD cards, so it isn't a PC issue).  I then put it back in the camera and hooked up the camera directly to the PC and could transfer files over no problem.
Does the format for the SD card just not work with windows?  What format does the camera use?
Thanks.

i always format the microsd card on the drone.

I have had the best luck by NOT formatting at all. Works in my mini2, air 2s, and my PC reads it just fine.
