Can't seem to get the Mini to recognize my Sandisk Extreme 64GB SD card. Works fine in my PC and my GoPro. Tried reformatting in both, Mavic won't see it. Any ideas or do I need to grab another SD card? Seems odd that I can record 4k film on my GoPro without issue but the Mini can't even recognize it...I tried an old 4GB card I had lying around and it worked but only for about 15seconds at a time and it'd stop recording. Not sure why but I'm guessing because that one is an old, slow card. The Mavic didn't throw any errors, it'd just stop recording after 15-20 seconds.
