Alright, so due to my desperation on this issue I decided to make an account here. Lately I bought 2 microsd SDHC cards, and they were brand new. I did the whole method of powering off the switch, inserting the card, e.t.c. But when i turned on the Switch I didn't get the update to format the SD card, and I tried again with the other card. Both weren't read by the SD card reader which sucked because I also bought another one not long ago and it didn't work either. Brought it to my friend to test it out on his Switch, and it worked on his. I knew it was the SD card reader but I didn't know what to do. I never teared down my console (Other then my 3ds to get a sd card from there) and I am kind of desperate. I really need help on this because I need the storage, and it sucks knowing that I am not able to use my sd cards.
