Check if movie is in a list from web interface
Hello! Migrating from IMDb and have a basic question.
From a movie page, how do I know if that movie is already in one of my lists?

On a Movie or Series page, you can see if you have added it to Favorites, Watchlist and/or Rating.
It is not possible to see if it is already on a list created by the user.

Also, if it is, how do I remove it from it?

Click on the Rating, Favorites and Watchlist Icons or Shortcuts.
On a list created by the user, you can only edit the list.
