I can no longer edit my forge map in halo infinite

Custum Browsing is where people can join your forge map that you made, people online can join and play your map that you created in forge. I thought when season 7 of halo mcc came, that any halo with forge in the mcc would be Able to have custum Browsing on it, but it's only reach. I'm wondering if halos like halo 3 , halo 4, and halo 2 anniversary will have custum browsing, I made some pretty cool maps on those games but not halo reach.

When she says this is one of 3 forge maps, I assume she means like forge world, and that we indeed can edit other maps on the game?

The game does not support mods, so the answer to that is no. However, you can create maps using the Halo Forge options in the game, and the Halo forge app on Windows 10, these custom maps can be found in the multiplayer options in the game.

If you get the Far Cry games you can literally build ANY map in the world you want from any game. The forge in Halo is pretty good for re-creating maps but you are limited. But I have seen many maps from other games in Halo 3 and in Halo Reach. The
forge in H4 is even better so I expect even more maps from other games.

Also now I noticed halo infinite doesn't have permission on the PC.

Every other game does. Like halo 5 forge etc.

Halo 5 forge I had installed since it came out with permissions and it has never once moved on its own. Same with fallout 3.

Seems newer titles like fallout 4 doom eternal. Halo infinite and pretty well every indie game that requires app permissions are susceptible to this.
