The problem is described in the title.
I have Nextcloud 29.0.1, but the problem started with Nextcloud 28.
Instead of opening a preview when clicking a RAW photo, it downloads the file.
A little workaround:
The only way I can see a preview is when I have a JPG file in the same folder. I open the JPG that shows the preview, then go to the next image. In that case, I can see the RAW files.
However, this is very inconvenient.
