Favorites List on Mobile Doesn't Appear on Desktop?

Logged into same account on mobile and desktop. On Mobile I can create a a 'Favorites' list by "adding to favorites" any actor/movie/etc. But 'Favorites' doesn't appear on desktop, neither as a list of mine nor as an option to tag an actor/movie/etc as one...

Why bother creating a 'Favorites' list if it doesn't appear on one significant platform?
