"You need to buy this game" message after already buying.

Me too! Game is completely gone from "Full library" under My games and apps. Total BS.

I am having the same issue. Tried uninstalling the game but now it has disappeared and cannot reinstall it. Was also charged when pre-ordering the game.

Im having the problem that I bought the ultimate edition and it says its installed when I search for it on the microsoft store and that its purchased, but when I try and start it the game says I need to purchase it and it doesnt show up in my full library
along with several other games I own. I was also able to play it for the first few days as well.

And says you need to buy the game before you can even think about playing?

Im having the same issue with coldwar and it completely deleted the game from my console
