Re: ORF file import problem.

You are in the 'Right' place!  Version 2.4 is the 'Cloud' version, and when used on a computer (desktop or laptop) is referred to as 'Lightroom-Desktop'..!!

(How confusing)

I am primarily a "Lightroom-Classic" user, so not familiar with "Lightroom".

I can refer you to this link-

Add photos to Lightroom

Hopefully you find an answer there, or other users may reply to this thread to help you.

Note: Camera raw is only useful as a Plug-in for Adobe Photoshop! Not used by any Lightroom version.

Can you see the image thumbnails IN the Lightroom Library grid?

If you are viewing in Windows the generic ORF icon you see may need a specific Codec to make the image content visible.
