For those who aren't aware, the "Xbox Game Bar" is an app/interface that comes already installed by default with Windows 10/11 so you have it too. It's used to talk with Xbox Console friends from your PC, kinda like the "Shift + F2" Ubisoft interface, but pressing "Windows button + G". It's a cross platform chat & there you can also see what your Xbox friends are playing, chat with them, check Achievement progress, etc. You can open this interface even if you're not playing a game, so it will work even if you're watching a Youtube video, using Spotify, or reading this.
Xbox PC Game Pass has more than 100+ games & Rainbow Six Extraction is one of them, but it's the only game of those 100+ where the Xbox Game Bar doesn't work. If I try to open the Game Bar when I'm playing Extraction, nothing happens, so I have to minimize the game in order to open it, which isn't that bad. The real problem starts if I want to voice-chat with those Xbox Console friends, the Game Bar doesn't recognize when I press my push-to-talk button if I'm playing Rainbow Six Extraction at the same time. So basically, it's a PC Game Pass title but it doesn't support an important PC Xbox feature.
The other problem it doesn't affect me that much but I'd like to report it too. When you play a game in PC, the Game Bar recognizes it and it updates your profile as "Playing + the name of the game/app". Kinda like Discord. It's not the case with Rainbow Six Extraction, Xbox doesn't recognize it as a game, neither does Discord, so if you're playing Extraction you'll be ''Online'' in both platform instead of "Playing Rainbow Six Extraction". It affects me a bit because some friends send me multiple messages if they see me Online and not "playing..." a game.
