What is the definitive guide to syncing Lightroom presets from Scott Kivowitz?

I have a full walkthrough on this in my video “Lightroom Mobile Presets – Syncing Presets to Lightroom Mobile” on YouTube. In it, I show how to sync your desktop Lightroom presets to Lightroom CC and then to Lightroom Mobile using Adobe’s built‑in preset/profile sync.

You can also see my preset packs and related resources on my presets page, which I link below that video.

Are you mainly syncing from Lightroom Classic, Lightroom CC, or both?
