I tried to multi-quote a post and it said "sorry, not found" and when I try to quote a post it just brings me to the top of the page. Whoever the mod is here you might want to look at the user permissions.
Anyway, on formatting your micro SD card, you should use Exfat. Why? Interchangeability between mac and pc for one, but more importantly, better memory management . NTFS is better suited for hard drives. Of course, either will work.
Also,i tried a 256 GB microsd card and it was recognized fine.
