Xbox party chat issue's

If I am in a party on the xbox and go to multilayer lobby it puts you in game chat in the lobby, you can rt back to party chat but when you leave the lobby your party chat no longer works, you have to go in party options change to game chat then change it again back to party chat before your party will work or end up making a new party again. Thing is if I go in a lobby in a party it means A) I dont want to be in game chat to listen to anyone else or B) I’m going in with friends an just want to be in party chat not be forced into game chat then have to mess about to get my party to work again. This really needs looking at, seen as I got the 4 day early play game and could only get online yesterday (the 4th) and now with the party chat issue I have to say I feel I have been cheated out of something I should have had from day one, but the party issue is the thing that bugs me the most.
Thanks,
