I complained about this a little while ago.
After I upgraded from 32-bit Stellarmate to 64-bit I was no longer able to access the shared folders on RPI (I had Pictures, Videos and Logs).
Changed permissions - didn't help.
Today I figured this out.
On 32-bit SM those folders resided in /media/stellarmate/Elements/
On 64-bit they are in /home/pi/
Edited smb.conf accordingly - now everything works.
Just reporting. Might help someone.
