I have started facing this issue with Fireteam finder, Whenever I select a listing, I will apparently become part of the lobby but the fireteam finder screen will not move to the "Ready UP" page. I have no way to ready up and then I get eventually kicked from the lobby. When I look up on the destiny 2 companion app, It says that I'm part of the lobby, but there's no way to ready up there as well. I'm unable to join any fireteam finder lobbies this way. Please help !
