Force Mac to push iCloud Photos over to iPhone?

I've had iCloud Photos synced between all my devices for a number of years. If I take a photo on my iPhone, I can open up my Mac, iPad, Apple TV and it they appear instantly.

Today I have imported a ton of photos from my physical external hard drive into Photos on Mac and I named/organized them into albums and folders. The first 200 or so appeared on my iPhone straight away in the same folders I made on my Mac.

However, since these first 200 or so, nothing else has come through to my phone. It's been 7 or 8 hours since I did this, no other photos will appear on my phone, but all of them (including the new albums and folders) are appearing on my Mac.

Is there a way of me force pushing / force syncing what I'm seeing on my Mac over to my iPhone?
