Match the series first
Search the show’s full name and check its start year. Australian Survivor and Survivor are separate productions. The Vampire Diaries, The Originals and Legacies have separate season lists. A familiar actor is not enough to choose the right page.
Save what you finished
On a series page, choose the season and last completed episode. Save the checkpoint. If you only opened an episode or stopped halfway through, keep the previous completed episode as your reminder.
This is a manual checkpoint in your browser. It does not follow playback on another service or know which scene you reached. Use the viewing player’s own resume controls for that detail.
Compare with the latest episode
The episode updates list gives recorded air dates. Your country or viewing edition may have a different release schedule. Open the show and compare the actual available episode list before assuming an episode is missing.
Keep several shows separate
You can save a checkpoint for each series. My List shows those reminders together. If you rotate between The Rookie, FROM and a competition season, each keeps its own place.
Before changing browsers, use the backup tool. A list is easier to carry when the stopping points travel with the titles.
