Hi @Andrew_69 I have most watched channels displayed as shortcuts , noticed though a few there I have hardly ever viewed if at all. Can remove if wish but not edit. You may wish to set up the Universal Remote again and when you select Sky ensure it is the right region selected (may well be the case though) . If that does not work only thing I can suggest really is a Factory Reset if want to go down that route.
I tend to use Home-Tv Guide and Favourites (set up on the Q Box) anyway.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
