Faces (People) not syncing on new iPhone 17 Pro

Hello, I have a new iPhone 17 Pro and to my surprise, all my pictures have synched but not Faces (People). I have 5 pictures of my dog on my new iPhone and 2800 in my old one... is there a solution to this or is this Apple just rolling out features that don't properly work? Thanks.
