Can’t load play multiplayer menu

I push A on the multiplayer on the play tab and all I get is the flashing UNSC logo no menu to actually join game. Anyone know how to fix this?

This is not available yet there is specific windows that you can play Multiplayer if you are on the east coast it will be 1pm to 5 and 8 pm to midnight. All you can play right now is you vs bot custom and weapons drills.
