New iPhone XS People & Places People album not populating - nothing

I have a new iPhone Xs running iOS 12.4 syncing to MBP using Mojave 10.14.6 via iTunes version 12.9.5.5. Using usb cord to sync selected items - pics, music, etc..

The People album under People & Places will not populate. Can anyone help to get it working? Not sure what to do. Here is a pic of how it looks now. Have left the phone locked and plugged into power outlet days at a time and nothing shows in album.

Interestingly, the 5 has now changed to 7 pictures synced when I now look at the phone. It changed after I took these 2 screen shots to post.... Weird.

Solution 1:

Photos synced through iTunes won't carry over faces data. Instead, your phone will scan the library manually. It will do this in such a fashion that it doesn't interfere with your battery life.

If you haven't left it plugged in over night you certainly won't see much results
