I’m running Nextcloud Desktop Client Version 35.0.0 on Windows 11. I have synced my entire documents/pictures folders. Hosting my own server via TrueNas. I’ve enabled Virtual File Support. The documents folder is set to “free up local space”. The Pictures folder is set to “free up local space”. The “Camera Roll” folder within the Pictures folder is set to “make always available locally” None of the pictures get the Thumbnails to render in Windows Explorer. If I copy one of the pictures folders to my local drive such as c:\temp, they all render immediately. I have a different computer, where everything is set to “make always available locally”, and all the thumbnails render. How can I fix this? ---

Does anyone know how to get a preview Thumbnail for videos?”.
