This was broken before the latest update, so at least 4-6 months now, but friends cant accept game invites through the game, they have to tab out and accept them through the xbox application or else they fail to connect with a different cross server game error message. Since I am bug reporting a few things figure I add it to the list. We are all using Xbox Game Pass and playing on a PC, and need to alt tab out to accept the xbox invite through the xbox app. It used to work prior to sometime at the end of last year, I think it was broken when the Samurai update came out.
