Here is the issue that seems to extend into other areas.
I have a shared folder (smb) on ReadyNAS104. I can add a bookmark etc works all fine BUT when I download files from a browser/internet and save them in any of the shared folders, they are hidden. I can find them alright but it is just annoying. Also I get a funny UNC path /usr/1000/...etc
Another issue is when using Zoom (install or web) I cannot access files shared in chat or upload files.
