Here's a British IPTV frustration that happens with every series: the "Next Episode" button on your IPTV Reseller Panel works for episode 1 to 2, but breaks between episode 5 and 6 because UK broadcasters sometimes split series into "series 1 part 1" and "series 1 part 2" — and your panel doesn't understand the connection. A reseller in Southport had British IPTV viewers bingeing British dramas complaining that "Next Episode stopped working halfway through the series." His IPTV Reseller Panel used simple season+episode numbering (S01E01, S01E02). But many UK broadcasters label a 12-episode series as S01E01-E06 and S02E01-E06 — a second "season" that's actually the same series. British IPTV viewers watching Vera or Shetland would hit "Next Episode" after episode 6 and get nothing, not realizing the panel thought they'd finished the series. British IPTV audiences need series linking that understands UK broadcasting conventions. What actually works is smart series detection that follows broadcaster-defined series groupings, not just sequential numbers. A reseller in Spalding switched to a panel that uses broadcaster-provided series IDs to determine what's "next." His British IPTV viewers could binge entire 12-episode series seamlessly. The pattern that keeps showing up is that naive episode numbering breaks on UK split-series conventions. Ask your provider: "How does your 'Next Episode' handle UK series that are split into multiple seasons? Does it use broadcaster series IDs or just season+episode numbers?" If they use simple numbering, your British IPTV viewers will hit dead ends halfway through every long-running British drama.
