Our build, or somebody else’s
The Neo4K app is optional, never required. What a NEOA- order hands over on an Xtream delivery is a login - host, username, key - and any player fluent in that protocol reads it, so the Samsung and Apple routes further down are not second-best substitutes; they are other windows onto one Neo 4K account.
Our build is worth having where it is available because it spares you the mapping step: the three values go in once and the pack you bought arrives in the order it was built in. Where you use a third-party player instead, prefer its Xtream option over its M3U option. Xtream draws the catalogue down a piece at a time while you move through it, and it is the one of the two that carries catch-up; a flat M3U hauls the entire list over before it will show you anything, and catch-up has nowhere to live in it.
