I am now starting to see very long load times to SD cards. I use the WIFI SD cards. This is a new issue and seems to coincide with another user seeing slow transfers to SD cards.
I am not sure what may have changed if anything.
The green loading bar goes about half way and sits for 4-5 minutes on just simple files.
This is a new behavior as file transfer from S3D to SD have always been reasonably fast.
