Halo 5 Multiplayer Problems

First I want to say, thank you for taking the time to support us players! I appreciate that time and investment that y’all put into the entertainment that we enjoy.

I want to write to say that I have no problem playing Halo 5 by myself. I bought the game, the xbox, and the membership to play with my friends. I have not been able to play with my friends for some time now and and wondering what is being done about it. Is there anyway that I could help contribute to the solution?

When a Fireteam is made and we select a game type we get into the game but it never finds other players. I stays in the loading screen until we tell it to stop and we disband.

Thank you again for your time and I look forward to hearing back from someone.
