I discovered a few days ago that I can swipe up on a picture with my iPhone to associate all found faces with known contacts. This is an amazing feature and I wanted to do the same with other pictures that I have on my PC.
So I went to iCloud Photos created a new album and drop some vintage pictures of mine. I can then see this album on my iPhone. However, when I swipe up on this very album pictures I don't have the option to find faces.
I have an iPhone and an iPad and a PC. Would it be possible to sync my pictures across my Apple devices and tag faces and locations?
