No thumbnails for files under Nextcloud folder

[s1291]

Hi,
I've just installed this extension and it seems to work well for many SVG files in regular locations. However, it doesn't generate preview thumbnails for SVG files located in my Nextcloud folder, for example:

C:\Users\USERNAME\Nextcloud\Home-Cloud\04-Graphics\Wind-Energy\wind-turbine

This issue might not be limited to Nextcloud. It could also affect other synced folders like Google Drive or Dropbox, but I can't test those since I don't have them installed.

A screenshot is attached below.

Thank you

Hm I've heard cloud sync folders can be finicky with thumbnails. It works for me with dropbox at least.

I looked in my onedrive folder and seems like even some PNG files start acting weird when I mark them as always sync to device or even just download them:

I think this is an issue with Windows
