One thing I’ve learned about the SD cards is the formatting. When formatting them on my computer, there’s an option for FAT and EXFAT. I’ve always used the exfat for my Gen 1 cameras… but XB and X pros will only take cards that’s been formatted to the fat setting. Also, one of my XB’s wasn’t dated right… I downloaded a file to my sd card and followed the instructions and it’s working properly now. If you’re not on their FB group, do yourself a favor and join. It’s searchable, so you can get info about various problems people have experienced.
