QNAP Serviio V2 MediaBrowser not showing titles

Serviio V2 - ARM x41 version.

This has been set up and the actual content is fully accessible via DLNA from my TV (Sony), iOS (iPad, iPhone apps), DVR (Humax), etc..
However when I try to view the contents via MediaBrowser most of the content is missing.
In some instances (e.g. Audio) the categories exist but no titles are displayed.
In other instances the (e.g. Images) the presentation structure is incomplete.

On Windows 10 Pro and occurs in MS Edge, Chrome and Firefox.
On iPad/Safari it is the same.

Also Windows Media Player also fails to find the material.

Update.
The MediaBrowser problem appears to relate to the new "User" feature.
Ticking "User with access" box for each library seems to resolve the problem.

It does not seem to affect the DLNA access, so I'm a bit puzzled what the ne "user" function adds.

Still its working now.

Windows Media Player still doesn't show the content, but I can live with that.

By default the user profiles are enabled on MediaBrowser, but not for connected players. However, you can assign users to both shared library locations and individual players to control access to content. There's also a way to re-enable anonymous access for MediaBrowser (https://www.serviio.org/index.php?optio ... icle&id=43)
