Find the chapter without reading ahead
Open a series and choose its episode guide. Expand the season you need rather than scanning later episode names, which can reveal developments. You can also search a compact query such as Sherlock S1E1. When the chapter exists in the catalog, the result leads to that place in the guide.
Save what you finished
On the series page, select the season and episode you last completed, then save the checkpoint. This is your own note. External playback does not automatically update it. Keeping the meaning consistent makes returning after a break much easier.
Different season groupings
A destination may organize a special or a later run differently. Compare chapter names and air dates when numbers disagree. The guide uses dated episode records, not a guessed season filled with unnamed future chapters.
Open Latest episodes to find returning programs, or My List to review your checkpoints together. A backup can move those notes to another browser.
