Do iCloud shared albums take up space on subscribers' iPhones?
I know iCloud shared albums don't take up iCloud storage, but do they take up regular iPhone storage space? I have several people who've said they're wary of joining shared albums because they're worried about giving up the iPhone space. I don't think the photos reside on their iPhone because they're on the iCloud servers instead, but I may be wrong. Maybe the photos are downloaded to the phone from iCloud in order for subscribers to view them.
