Shared Photo Album-Not All Pictures Uploading

Yesterday, I created a photo album that I shared from my iPhone to my MacBook. It contains 835 pictures. After a few minutes, the pictures all appeared on the album on my phone, and eventually, the pictures started showing up on the same shared album on my laptop. However, the same album on my MacBook shows that it only has 735 of the pictures, and the rest are not uploading onto my laptop. It has been over 24 hours and the last 100 pictures have still now shown up on the shared album on my laptop. I have tried restarting it and photo app, and simply waiting as well, but the pictures are still not showing up. And, the missing pictures are random ones throughout the whole album; not just at the end of it. Am I doing something wrong, or do I just have to wait more?
