Adding Episodes to Lists

I can no longer add individual episodes to my custom lists. I have tried on the website and iOS. The option to add is simply gone.

I have been a dedicated VIP user for over a year and love making custom lists of interconnecting shows/movies.

Is this due to the most recent update? Will the custom list feature be fixed? Please help.

are you using the classic site or the new site? in classic you should be able to keep doing that, but on the new site, adding episodes to lists isn’t supported currently iirc
