Identify what actually started next
Record the title that ended and the title that followed it. If the second item belongs to another series, that can fit the documented suggestion behaviour. It does not by itself prove that the service skipped an episode within the original series.
This matters when following a structured series for study. Keep the series episode list as your reference for sequence. A recommendation played after completion is a discovery choice, whereas the numbered next episode is part of the sequence you intended to follow.
Change the preference in the mobile app
The current help article places autoplay in Settings for both iOS and Android. Inspect the switch on the phone or tablet you are using and choose whether automatic continuation suits this particular session. The article does not establish that changing one mobile device changes every television or browser.
After changing the preference, use a programme you can finish to check the outcome on that same device. Avoid changing several unrelated settings at once. One observed end-of-programme result is much easier to interpret than a session involving a new account, another device and several changed controls.
Plan a bounded viewing session
Suppose you have forty minutes and deliberately select a thirty-five-minute documentary. A suggested programme starting afterwards changes the practical end of the session, even though the original documentary finished normally. Decide whether you want that continuation before settling in.
If unexpected playback persists, report the mobile operating system, app version, preference state and the two programme titles. Describe whether the next item began after the first reached its end. That detail separates autoplay from an accidental tap, a resumed item or confusion over which episode was selected.
