I’ve tried reformatting the SD Card and still get the same issue. I don’t know if this is still read only or how to change it. I just formatted by right clicking selecting format to exfat. Didn’t change any settings.
I've tried to use the FTPD - I can connect and see the files/folders via Filezilla but when I try to transfer anything across to the Switch SD card I get Error code 2345-0021. I've reformatted the SD card and tried again and still same issue.
Any ideas?
