Channels we have not watched

@DebInMA Thank you so much for your post on your concerns about your last watched programs. The last watched feature is specific to each device and stores that information from the local device memory. Each box and Xfinity ID with the Xfinity Stream app have their own memory, even if you do not stay on that channel for very long like an accidental tuning to the wrong channel in the guide it would still register in the last watched options.  You can clear the last watched options by checking the steps here. https://www.xfinity.com/support/articles/x1-last-watched-clear-history   You can also check out this page here to see how to set up controls to ensure any content you do not want to be accessed is blocked on the box in question. https://www.xfinity.com/hub/parental-controls
