Is there some way to force Photos on Mac to sync with iCloud? Many times when I import pictures they do not get uploaded to iCloud. It's very flakey. I checked my iCloud storage space and I have plenty of remaining space so I don't know what the cause could be. I've lately been resorting to uploading the images to Google Drive then downloading them to my phone.
EDIT: I believe I found the cause. If the photos are too big in size (over 2MB) they won't sync. Is there some setting to adjust this?
