You can add programmes and series to your watch list.
This only relates to programmes that are on catchup apps and only whilst they are available. If you use the Great app for example, shows disappear normally after a week.
If you have an existing YouView box, the watch list is the same as this box.
Please remember to mark Solved Posts with Best Answer. Doing so helps other customers and saves TalkTalk's Support Team time by only looking at unsolved topics. Thanks, Steve (a fellow customer).
