One of the suggestions I received from the fellas at support when dealing with the firmware update fiasco was to reformat my sd card using exFat. Dude was very confident that was going to solve my problem. I was skeptical but did it anyway. Needless to say, it had nothing to do with the Firmware problem but has resulted in a new problem. I'm getting a message in the app saying "Reformatting is suggested" the app doesn't show how much room is on the card, and the option to reformat the card in the app is not available anymore. I tried reformatting it back to Fat32 but that didn't help. I can still record video and take pictures but I have no way to know when the card is full. Any suggestions? I'd call support buy my confidence in those guys is low right now.
