I've got a samsung tv and installed the smart iptv app. I've got an iptv service working on it and it's been working perfectly. Now all of a sudden it won't let me watch any UK channels (sports, movies, freeview etc). All other channels seem to work only the UK ones won't load. I've contacted my provider and they tell me it must be my ISP blocking it and I need a VPN. Does this sound right as it was working fine and it's strange all other channels are working just the UK aren't?
