iPad Pro Beginner's question on sync'ing with Mac

[cyberstudio]

My daughter took pictures on her iPad and had an account on my Mac. In Finder I am able to backup her entire iPad both with a USB cable and over WiFi.

So in Finder I set up "sync" under the photos tab and click the "sync" button. Sure enough the photo library on Mac goes to the iPad but it appears to be unidirectional. None of the photos are sync'ed from the iPad to the Mac at all. I turned off Photos in iCloud on both machines but made no difference.

What might I have done wrong?

I opened Photos on Mac and it lets me import if connected by USB cable but the icon representing the iPad disappears as soon as I disconnect the cable. No WiFi.

I guess I have a fundamental misunderstanding of how this is supposed to work? I was expecting that while I go to sleep and the iPad is charging they would "sync" photos bidirectionally with each other?

Just like with any iPod or iPhone, pictures sync only one direction and that is from computer to mobile device. If you want to import them via cable, import them just like you’re doing it in the Photos app and like you’d have done with any conventional digital camera.
If you want to use iCloud photos, activate the feature on the devices in question and they’ll sync to the cloud if there’s enough iCloud storage.
