After this I also added
[userdata]
comment = kodi userdata
path = /root/.kodi/userdata
writeable = yes
guest ok = yes
create mask = 0644
directory mask = 0755
force user = root
To the end of my /etc/samba/smb.conf to allow me to copy over my existing Kodi setting from my other RPi’s. The trick was that it uses the config from the root user and not the pi user.
