When Lightroom Classic syncs photos that were uploaded into the CC cloud, it loses any pre-assigned folder/albums. Can we please have this fixed?
If by "photos" you mean the original, hi-res or RAW file, LR Classic NEVER syncs those to the Cloud. It only syncs the Smart Preview so you can use your LR Mobile on your iPad, etc. If you are switching from Classic to LR CC, and uploading your entire catalog, do yourself a favor and don't!
