Album in LR Library

So... Is it really fact, that the people I share the album with don't see the rating stars or the flags to approve/disapprove of a picture or did I just miss the settings to show them?

My 2nd question is: is there really no filter option to show only the pictures that got a like (heart) or a comment?? 

Pretty timeconsuming to look again through all the pics to find out, which ones the client liked. I hope I just looked in the wrong place 🙂
