Ultimately, my goal is to migrate all of my photos from Google Photos to Adobe Lightroom CC and eliminate the Google storage charge I am paying each month. Adding all of my photos to one collection seems clunky and organizing 30K+ photos into regular collections seems too time-consuming. It is only available for regular collections (and slide shows?). I tried using a smart collection to do it- all photos dated 2015, for example-but the sync option is not available for smart collections. It appears that my photos I have in Lightroom Classic CC have to be added to a "Collection" before they can be sync'd to Lightroom CC.

In Lightroom Classic CC I imported the Google Photos folder, leaving the photos in their current location. I have Google Drive on my Mac and have set it to sync the contents of my Google Photos account (~150 GB) down to my Mac. I can confirm this works pretty flawlessly with Lightroom Classic CC, but I'm still not completely sure how to sync to Lightroom CC.
