Not being able to do all Halo 5 can offer

Ever since I got my xbox one halo edition in November I haven’t been able to access all aspects of the game. Have never been able to spectate a game or have the option to spectate when friends are in the game. Can’t do anything with the theater option. No saving videos, bookmarking or even replaying. Can’t create my own custom game option. Can create a custom game using the preloaded game types but can’t save a special variant. With the lastest patch the cartographers gift, I haven’t been able to do anything at all with forge. Hopefully someone has some insight on what can be done about all or some of the issues I have. Thank you.

No one has any ideas?
