Thanks for pointing this out! (I was literally just thinking about this today!) I remember on the WiiU and the 3DS you had to format any USB drives or disks that were bigger than 32GB, and formatting it to (can't remember if it was FAT16 or FAT32 now). But I did this on both my systems and they worked perfectly even a much higher than the 32GB that those two consoles natively supported. But if the switch doesn't even need this step, and just works straight away like you've said here, that's even better! How many GBs was the SD Card that you used when you did this?I just popped the brand new sd card into the switch immediately and the switch handled it. No extra formatting needed.
