Xbox game pass inactive in BO6

Hello, first of all, I’d like to greet everyone who reads this.

I’m aware that today there was or still is an issue with users who have a Game Pass subscription. My main problem is that when I try to play the Zombies mode in BO6, as soon as I access the corresponding section, it directly prompts me to purchase the “game” itself. This is despite the fact that the Game Pass subscription provides this benefit.

When I check other games, they appear with the Game Pass advantage, but BO6 does not. Does anyone know why this might be happening?

I’d like to clarify that I play both on PC and through Xbox Cloud Gaming (xCloud). On Xbox Cloud, I have no issues launching BO6. However, the problems arise when I try to play via Battle.net. Personally, I prefer playing with a keyboard and mouse rather than using a controller.
