My issue is that we can no longer see the date on which a song has been added to any/all playlists. I realize you'd like us to subscribe to/follow playlists and then pay attention to the notifications, but I follow so many that it's impossible for me to catch them. Therefore, please bring back the option to scroll right and see when the songs have been added. This also helps me to stay current with music/collaborative playlists.
This is still working when you maximize your Spotify window. If the window is too small the 'date added' column will auto hide.
There exists an idea to always show that column no matter how small the window is here:
You might want to add your kudos there. 😉
