Confirm that you are cleaning the right list
Continue Watching contains programmes you started without finishing. Favourites is a separate collection that you deliberately save. Before changing either list, identify whether the unwanted tile appears in the unfinished-programme row or the saved Favourites collection.
If a programme appears in both places, removing its unfinished-state entry is not the same request as removing it from your saved collection. Decide which result you want, then check that specific collection after the change. This prevents a successful action in one list being mistaken for a failure in the other.
Use a supported removal interface
For the website, SBS describes the three-dot menu on the item in Continue Watching and its Remove action. Mobile apps also offer an item menu. Other documented television interfaces use a long press, but the help explicitly separates Android TV, Google TV and Fetch as lacking direct removal.
Open SBS On Demand on a supported secondary device that you control. Confirm its signed-in email matches the television account, locate the unwanted unfinished programme and remove that item there. There is no need to create a new account merely to find a different menu.
Return to the same account on the television
SBS says the change can sync when both devices use the same email address. Compare account identity before repeating the removal. A household with more than one SBS account may otherwise edit one collection while continuing to inspect another.
If Continue Watching itself is absent, SBS suggests signing out, restarting the device and signing in again. Use that guidance for the actual missing-row problem rather than treating it as the first answer to an unavailable item-removal control. For an unresolved sync issue, record which account matched, where removal was completed and what the television still shows. Do not publish the full email address, password or sign-in code in a public screenshot.
