If the microSD card is not compatible with the console, replacing it with a compatible type may resolve the problem.

Nintendo Switch Micro SD Cards - Cheapest Memory Cards Best Nintendo Switch Micro SD Cards - Cheapest Memory Cards

I do have a 32gb microSD I'm not currently using, so that will most likely go to the Switch at the start. If a microSD card is inserted or removed while the console is powered on or while in sleep mode, you will be prompted to restart the console. The average first party Nintendo Switch game sits at around 6.7GB (though there are outliers on either side of that figure), so it's fairly easy to work out which size you need based on your current or future library. Indie games are tend to be far smaller, so there's wiggle room here as well.

So again, no offense, but you're rather late to the party, to say the least, seeing as my last comment in this thread was from November 2017...

SanDisk 256GB microSDXC card for Nintendo Switch consoles up

Switch don't benefit on read speed on expensive cards, so just buy standard Sandisk SD cards and similar. GamerXiphos I hope but I'm pretty sure they would have mentioned it. It doesn't just mean that it's faster there's actually more pins that are needed. I own a Fujifilm x-pro 2 with 2 card slots and only 1 slot excepts the much faster uhs-2. This would be a huge selling point for Nintendo wouldn't it? Going from 95mb to almost 300! So, is this ADDED to the internal 32GB, or does it turn it off like on Wii U? (I'm pretty sure my 12GB PS3 Superslim turned off the 12GB when I installed an 80GB drive in there as well.) We all know of the troubles with Wii U storage. So, if you buy a 64GB card, do you then have 96GB or only 64GB? A 64GB card might be enough for awhile if they work together, but not if 32GB gets turned off like on Wii U. Such a pain that was. Still waiting on the 1tb micro sd cards to come down in price before I buy (seeing that I will need at least 6 of them).

Kingston memory cards for your Nintendo Switch Gaming Console.

Jaded_Drybones Not "put their foot down" in a harsh and thoughtless manner, but to an extent, and if we have to believe EA and Ubisoft, then they have been in talks for quite a while already, so potential problems like these will more than likely already have been discussed or even ironed out. The only card I have had for on me so far has been a Samsung 128GB. but that may have been overuse. starfox007 I've only been to the one in Pattaya.They haven't had much business from me yet as I bought nearly all my Wii U games digitally. I did buy a Pro controller from them though. Got a SanDisk 128gb Extreme microsdxc card for 56.99 on Walmart dot com and that'll hold me over for a long time. I'll be buying mostly retail for the big games so I won't need to worry until a year or two in which prices will be even lower.
