So I'm trying to start the MW 2019 campaign on Xbox Series X. But for some reason the only option available is "Purchase". What? I've purchased it when it came out. I've played it in the past month. Why do I suddenly have to purchase it again?

Even pressing the Purchase option doesn't even do anything. It just takes me to the second screen with the only option being "Buy now &&1". But nothing happens when I try pressing it. Can literally do nothing.

I can see it still being installed on console. I can't buy it on the Xbox Store. I can only start it since I already have it.

Has anyone else ever run into this problem? Any idea what to do?
