Versions App - support for file versions on local external storage?

I am wondering if the versions app supports file versoning on a local attached USB hard drive. My server itself runs NC 11.0.3 on a Raspi3 from SD. The hard drive is mounted as local external storage.
File sync works with Nextcloud app on Win10 device without problems. If I am syncing files to the local storage, i.e. to the SD card the versions are shown on the details tab on the web interface.
This is not working for files on HD, the versions tab is empty.

Any clues were to configure this setting, the user and admin manuals dont provide these information or at least I cannot find anything about this subject.

Many thanks in advance for everybodies help.

Kind regards, gst

Any update on this question? I guess this simply isn’t supported, is it?
