File Sharing
I've setup a new mac Mini with MacOS Monterey 12.2 (but had this problem before at customer site).
when I connect via SMB file sharing with two different sharing only accounts and one user changes the name of a file (doesn't seems to happen with a folder) the on the other user the name changes to a ? and the file becomes zero bytes. reconnecting solves the problem but that's no usable solution.
Also when the first user adds a tag it does not show on the second user.
Mac mini 2018 or later
