Tap once to keep a title
The heart on a card and the save button on a title page perform the same action. A selected heart means the movie or series is in My List. Tap it again to remove that choice.
Episodes have a separate marker
Select the last completed season and episode on the series page. The checkpoint remains available with the list, even if you are returning much later. It does not measure minutes watched.
Know which browser you used
A private window, another profile or another device can have different storage. Logging into an outside viewing app does not synchronize PrMovies choices.
Keep a copy before a change
Create a list backup before clearing browser data or replacing a device. You can merge recognised entries into another browser without replacing its existing choices.
