Save from the title page
Select Save to My List after checking the year and cast. The button confirms the saved state. Open My List to return, then use the same title-page button to remove a production you no longer need.
Use one meaning for a checkpoint
Record the last completed episode, not the one you intend to begin. Select its season and number, then save. Clear the reminder from the series page when you want to start again.
The list lives in this browser
Another browser, device or private session can have a different list. There is no automatic account sync. Website storage removal can erase saved titles and reminders.
If an item is missing
Check where you originally saved it before changing storage settings. Keep a separate bookmark for a recommendation that needs to survive beyond one browser. Clearing more data will not recover a lost local save.
