Has anyone successfully formatted an sd card from the settings menu on the official sailfishX port?

I have an empty 128 GB card i was trying, but when i select format it takes me to the 'delete all files' button, which i press, but when i try to format again the same thing happens and no format.

If i want to use btrfs on a card this size do i need to format this externally to the phone, or is this pointless because of the btrfs driver issue mentioned up thread?
