I don't even understand what this feature is supposed to be. All I know is that the share screen _used to_ work really well! It used to show my most frequently contacted friends / family across applications (eg. Whatsapp vs Hangouts vs email) and it was a breeze to share content. Now... It shows the correct contacts for ~1 second, enough time for my brain to think oh maybe I should try and oh nevermind it's gone.
