Hello and welcome,
To answer your first question. When you open Creator you will see your published faces. Each face will show the number of synchs on the right at the small watch icon. (If you cannot find that, let me know. I'll post a screenshot for you.)
As to the Likes, they show up on the screen of my phone via the phone app. Make sure Push Notifications is checked in the Settings of the Facer phone app.You can add your like to a face using the phone as well. Find a face and click the heart icon. That will add the Like.
