@anon21401411 Do you have perhaps some further advice about how to clarify my question? I have tried to rephrase it here, thinking that this one was too complicated.
Basically my question is very simple: I wonder if files are supposed to appear automatically on the other side of a Shared folder through the ownCloud sync client; or if a refresh using the web browser is always needed. I suppose that many readers of this forum know the answer to this question (Shared folder seems like a very useful feature, and if one has used it, one will know if files are synced correctly as this seems like a must-have functionality). But I received no answer, and ignore why.
In particular, is it clear why the details such as OS, database, and the like can’t be provided in the case of this question, and are unnecessary anyway?
