Nintendo released a new Nintendo Switch stability firmware update on 7th June and it was taken down after a few hours as in some cases the system couldn’t find a network connection.
They also noted that some Nintendo Switch owners who had downloaded the update and then tried to use a new microSDXC card with the Nintendo Switch for the first time were having issues with the SDXC Card being unusable.

Back and fixed
It seems that these issues have thankfully been ironed out as the update (Version 12.0.3) is now live once again.
