Shared albums and local storage
I have a couple shared albums that I am subscribed to from a family member. They two albums combined have about 8k photos.
I personally do not have any photos on my iPhone as I back them up to Google Photos. But my storage says I have 12.8 GB used from the photos app.
These albums are not mine/on my device, so how are they taking up space? I am under the impression that shared albums only take space on the creators/owners device. Is that not correct? Or am I experiencing an issue?
iPhone 11, iOS 16
