I have used LR Cloud for the last few years. Recently I loaded LR Classic onto my new desktop, because I felt I would get more features. I changed my mind and went back to LR Cloud, because it wouldn't sync to the cloud.
Now I am using LR Cloud on the desktop again, and they will still not sync onto the cloud.
What's the status of the cloud syncing in the Lightroom desktop app (click on the cloud icon top right)? And what specifically is not syncing....is it images that you have imported into Lightroom are not uploading to the cloud, or is it changes you have made to existing images are not syncing to the cloud?
