I tried setting one up when it first was released… terrible experience with random photos migrating to the shared library. Anyone got recent experience with it and they’re getting on better?

For example, I want to share holiday photos with my close family and friends but a normal shared album compresses the images so would ideally use the Shared Library but I’ve already been burned so I’m a bit wary… (maybe I set it up wrong too, so open to suggestions for those who got it working properly!)
