Switch OLED does not read games "the game card cannot be read"

Hey there

I have tried a new daughter board already - trying another one to rule out a dud from Amazon.
It reads SD cards and can plug in headphones fine but just no game cards.

I have tried every single game in my library - tried them on 2 other switches to verify they still work (they do.)

Anything to point to?

Hello there,

I experience the same problem with my V1 Switch. I already tried different Game Card reader and also reballed GCBRG HAC STD module - still no luck.

Any ideas?
