Limit on number of folders visible using UPnP

[cs2001vlc]

Within VLC for iOS, when I connect and drill down on my UPnP server to where the bulk of my video files are (which are down 3 subfolder levels), I can only see 125 of the 300 folders that exist. Other apps don't have this problem with listing all of the folders, so I don't think it is a server-side problem.

I have had this problem for as long as I have had VLC installed on my iPhone 6+ (at least two years), so it is not specific to my currently installed version. I am currently using
VLC for iOS v2.7.8
iOS v10.3.1.

I realize that I could change how I organize my file system, but I'd rather keep it the way it is. Any other suggestions?

Also, I'm new to this forum... is there another way to report this as a bug, or is this post sufficient?
