I would like to get some more information from you. You posted this with a Lightroom CC for mobile devices tag and a LIghtroom CC for desktop tag. In your text, you mention Lightroom Classic CC. That is at least three places where you need to log in. Can you verify by signing out and signing into each client that they are all logged into the same Adobe ID?
Next: go to Classic CC, CC and CC on your mobile device and get me the installed version number on each.
After that, go to the Lightroom CC for desktop app on your laptop and make sure that syncing is not paused. Let is sit for about 10 minutes and see if you have presets and people. If not, click on the cloud icon and see if you have syncing pending.
