I have many SD cards for all my drones and for some reason I can't use them. I tried a SanDisk Extreme 32gb A2, SanDisk 64gb A2, and yes they are formatted FAT32. I even went into the camera and format the cards. Still its not recognized. The card will pickup and read in the ST16S but not in the C23. So I wanted to ask if I am missing something are is the recommended cards others are using?
