Lightroom classic vs lightroom cc: the collections

The process that I described is what is necessary to share images from Lightroom Classic because Classic is not fully integrated and part of the ecosystem that makes up the Lightroom cloud system. Any images that are imported into Lightroom CC should automatically be available on other devices that have the appropriate Lightroom mobile application installed. And if Lightroom Classic is configured for sharing the images should automatically download to Lightroom Classic as well. Of course, all devices using the Lightroom program for that device must be signed in with the same Adobe ID and password for this to synchronize properly.

In Lightroom Classic, if you click on the nameplate in the upper left-hand corner of the screen, in English it says, "Sync with Lightroom". There is an option there to enable. That must be enabled. Then you must create collections of images in Lightroom Classic. When you look at the collection in the Library module there is an  icon to the left of the collection name to click when you want to share that collection. After you have enabled synchronization, all you have to do is click on that icon to share the collections you want to share.

Seems to be a strange question. If you are using Lightroom CC then you ARE using the cloud.

Lightroom CC calls it "Albums", but these are the same as collections. It's just another name for the same thing. Smart albums (like smart collections) do not exist, however.
