LRC does not have sync option when creating a collection

Syncing collections is not only possible, it is the only way. Lightroom Classic does not sync the entire catalog, but you must turn on syncing for the catalog (and you can only sync one single catalog). Check that syncing is not paused, because pausing sync is like stopping sync.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
