I have no interest in organizing using CC's Collections and prefer to use folder hierarchy from Classic.
- Keep Import folder separate to catch problems!
Preferences, Lightroom Sync, Location, Specify location for Lightroom's Synced images
- Set
Catalog Settings > Metadata > Automatically write changes into XMP
so removing from Classic to add back some data is recovered - Video edits don't propagate, but if added to CC first, they can be moved among synced Collections
