Contaminated domination matchmaking

So I use custom search for dom so i play a game it starts matchmaking after the match says hagental base then contaminated pops up on the screen and then throws me in the lobby its constantly happening now then I start match making and it puts my party in a game and leaves me in the lobby which that parts not new but I figured yall could fix that in the 6 months people have said the xbox players are being left behind are we just not worth your attention because it seems like xbox gets all the problems that never get attention at all
