I had geforce now working fine on a 16gb SD card which I purchased to test Android on switch. Last night I decided to upgrade to a 128 gb card. I did everything i did before with the 16gb card it's the same brand and everything. But now I keep getting this error. I even checked it on my actual shield and it worked fine, but I'm continuing to get this error. If anyone has any suggestions it would be greatly appreciated. As I do not want to switch between SD cards.
