Thanks for all your help but I found out that for some reason the samba user failed to create at the first time with “smbpasswd -a kiwiheretic”. Found that out by typing “sudo pdbedit -L -v”. It is now showing as a folder on my android tablet and I have succeeded in copy pasting a file into the share.
Sorry , it’s the former but I don’t think my directory naming was the issue. I was in Reddit mode thinking to protect my privacy in case some crazed Redditor shows up on my doorstep with a machete but of course I realise this is not Reddit.
