That's because, unfortunately, Samba has a number of "moving parts" and we can't foresee every problem scenario that users might have. We have, to the best of our ability, explained the potential issues, but it's up to users to take this information on board and then sort out their own networks - be they Windows, Linux or other Samba servers, with or without SMB1 support, with or without Windows 10 to cause even more problems, with or without anonymous access, with or without LibreELEC OS mounts etc.
If we could give a single guaranteed "do this then this" solution that fixes this Samba mess for everyone, trust me we would have. If anyone feels they can do a better job of explaining how to resolve the different potential problems users with random Samba or Windows servers may face, please add something in the Wiki!
