How does Shared folder work?

Are there some regular users of Shared folders around?

As a user of ownCloud, I wonder, how is the Shared folder functionality supposed to work? Is my client supposed to receive automatically a shared file put on the server through the client from the person I share the folder with? The user manual does not tell about this, AFAICS.

I ask because for me it does not work, and I wonder if this is due to an older version being used on one of the servers we use (10.3.2 and 10.1.1); or configuration settingsā€¦

Please note: I am not a server manager; just a user. I just wonder if this is supposed to work; if not, no need to investigate further!

(I asked a similar question but with a much too complex explanation, which I think has not been understood; and probably using an incorrect category. I hope this question is better understandable; otherwise, please tell me. I hope it is ok to try again with a more focused question.)
