Share photo library multiple users + synchronize with iCloud Photo Library
I want to share one photo library between two users as well as to synchronize the library to respective user’s iCloud Photo Library.
I have followed this guide: https://support.apple.com/en-us/HT201517. It works advertised.
However, every time I switch user the entire contents of the library re-updates with iCloud Photo Library, rather than just update the latest changes. (Taking forever.)
Is there any way to avoid the full re-update?
