IPTV apps may crash when loading large playlists because the device does not have enough RAM, the app cannot parse huge M3U files efficiently, or the playlist contains thousands of channels and logos that overload the processor. Older Smart TVs especially struggle with playlists over 10,000 entries. Switching to Xtream Codes login, reducing playlist size, or using a lightweight player solves the issue. Premium providers like those recommended by Glanfy offer optimized playlists that load faster and reduce crashes.
