Yes ofc i installed it via the games pass app.
Don't mind the german, "Im Besitz" = "Owned"
As soon as i press "play" on the game pass app and the paradox launcher opens, the shenanigans start.
Like why can't i see my DLCs in the launcher like you do?
Why are they shown as "owned" but ingame not a single mention of anything owned?
All this different launchers different providers stuff sucks so hard

At first i was like, oh cool, let's try again, 10 Bucks for a month of CK3.
"Oh sad, can't play the DLCs, they are not included"
*Proceeds to buy DLC pack*
HOW am i supposed to know i am buying from xbox? i thought everything was good and i did the proper thing.
No way of knowing Microsoft does not tell Paradox of my little purchase.
I bet if i continued to buy the base game aswell everything would work magically.
But then i would have wasted the 10€ on the pass. What's the pass for anyway? To get me into a game? I liked it! Oh, no DLC included? Fair enough, take this money.
DLC bought - "JK we won't let you play your purchase, hehe. Basically we don't even know you purchased it, go blame microsoft."
Frustration intensifies
